Signal continuous wave conversion square wave method

The present invention provides a method for converting a square wave of a continuous wave of a signal, in particular, by using a continuous waveform of a signal and a reverse signal generated by the delay and the opposite action as a summing action and canceling each other to generate a relative point of intersection. The method of square wave shape can achieve the effect of data compression, which not only speeds up the conversion speed, reduces the memory capacity, but also can greatly reduce the manufacturing cost.

According to the rapid development of wireless communication technology, the traditional analog transmission method of electronic products is no longer the only source of audio signals. It is widely used to transmit high-efficiency and wide-ranging digital signals. Traditional audio signals are transmitted. It is a continuous waveform curve, so that the digital signal waveform must occupy a considerable memory capacity space, and it will cause its transmission rate to be slow, and the transmission and reception is not easy, and the signal transmission and transmission process takes more time.

Therefore, some operators have developed such a signal that can be sampled and converted, and become a simple storage and occupy a small memory capacity. As shown in the sixth and seventh figures, it is a conventional signal receiving block diagram. The waveform comparison circuit diagram receives an external signal through the antenna, and generates a repeated periodic signal through a low noise amplifier (LNA), a mixer (Mixer), and an oscillator (Oscillator). After the amplifier (Amp) is demodulated, the data format can be obtained by signal conversion. The waveform conversion method can be integrated circuit (Integrator Circuit) and attenuation circuit (Diminution Circuit). Or a Peak Detector Circuit generates a predetermined waveform and transmits it to the non-inverting (+) and Inverting terminals of the comparator in synchronization with the original signal continuous waveform (- After the comparison, it is converted into a square wave waveform output that can be used by the digital signal. In the process of sampling the original signal continuous waveform and the predetermined waveform, the peak and trough transitions are first approached. The overlap occurs to form a complex intersection point (Intercept Point), so that the intersection point can be detected for comparison, and the waveform is amplified and converted into a square wave waveform. However, the important delay time required for the sampling cannot be obtained. And because the current comparator processing speed is slow, such as the use of audio and video signals, it is easy to produce noise or picture delay, etc., if the faster processing of the comparator, but will increase the overall manufacturing cost, but The problem is still not solved, and it does not meet the consideration of economic benefits.

Therefore, how to develop and design an error that can be caused by the above problems and their required delay time growth without changing too many original architectures, is the inventor and engaged in this The industry is eager to study the direction of improvement.

Therefore, in view of the above-mentioned deficiencies and shortcomings of the above-mentioned practices, the inventors have collected relevant information and, through multi-party evaluation and consideration, have designed the continuous wave conversion square wave of this signal through continuous trial and modification through years of experience in the industry. The invention patent of the method was born.

The main purpose of the present invention is that the receiving device generates a continuous waveform of the original signal for receiving signals, and copies a delayed signal continuous waveform according to a predetermined delay time, and defines the coordinate waveform on the coordinate axis of the original signal continuous waveform, and then performs a reverse action to generate a reverse To the continuous waveform of the signal, an intersection point is formed near the peak and the valley turning point. Thus, the summing action can be performed on the two waveforms through the adder, and the effect of canceling the two waveforms mutually produces a relative point to the intersection point. The amplitude of the square wave waveform depends on the predetermined delay time. It only needs to transmit the square wave waveform to the amplifier for amplification. It can be used to reconstruct the digital signal waveform without setting a high-speed device, or the time to rise or fall according to the square wave waveform. The analog-to-digital sampling of the original signal continuous waveform is performed to achieve the purpose of data compression, which not only speeds up the conversion speed, reduces the memory capacity occupied, but also greatly reduces the overall manufacturing cost.

In order to achieve the above objects and effects, the technical means and the configuration of the present invention will be described in detail with reference to the preferred embodiments of the present invention.

After the continuous waveform 1 has the same ripple shape as the delayed signal continuous waveform 2, the delayed signal continuous waveform 2 is defined on the coordinate axis of the original signal continuous waveform 1 and moved to the right by a certain pitch, and the moving pitch is required for the delay oscillation circuit 6. The delay signal continuous waveform 2 is set to a predetermined delay time distance, and the delayed signal continuous waveform 2 is formed into an overlapping intersection type with the original signal continuous waveform 1, and then the backward signal continuous waveform 2 is reversely operated by the reverse conversion circuit 7. And the reverse signal continuous waveform 3 with the opposite corrugated shape will be close to the peak and trough turn The overlap occurs to form a complex intersection point 4 (Intercept Point), so that the complex intersection point 4 of the two waveforms can be sampled and synchronously transmitted to the adder 8 for the summation action, and the effects of the two waveforms cancel each other out In turn, a square wave waveform 5 having a transition state relative to the intersection point 4 can be generated. The magnitude of the amplitude depends on the delay time, so that only the square wave waveform 5 is transmitted to the amplifier 9 for amplification, and there is no need to set some high-speed devices, such as high speed. The comparator or the high-speed amplifier can reconstruct the digital signal waveform, or perform analog-like digital sampling on the original signal continuous waveform 1 according to the rising and falling time of the square wave waveform 5, so as to achieve the purpose of data compression, not only can speed up The conversion speed and the reduced memory capacity can also significantly reduce the cost of manufacturing.

The reverse signal continuous waveform 3 is overlapped and intersected on the coordinate axis of the original signal continuous waveform 1, that is, the delay signal continuous waveform 2 is moved by a predetermined delay time, and then reverse action is generated, and the original A plurality of intersection points 4 are formed at the overlapping intersection positions of the signal continuous waveform 1, and are synchronously transmitted to the adder 8 for the summing action, and the adder 8 is used for the summing operation mode, when the original signal continuous waveform 1 and the reverse signal are continuous. The positive and negative voltages of waveform 3 add up to each other to form an offset effect, and then transmit to amplifier 9 to amplify the square wave waveform 5 zero-value band in the vertical direction (or horizontal direction); if the original signal is continuous waveform 1 and When the positive and negative voltages of the continuous waveform 3 of the signal are summed to form a difference, the amplifier 9 is amplified and outputs a square wave waveform having a certain amplitude and amplitude in the horizontal direction (or the vertical direction); The square wave waveform 5 amplitude is obtained by amplifying the amplitude of the predetermined delay time by the amplifier 9 to obtain a desired amplitude, and a continuous square wave waveform 5 can be generated, such as in video and audio. It is not easy to generate a fault such as a treble or a picture delay on the signal, and the important delay time required in the sampling process can be easily obtained by the method and the step flow of the present invention without changing too many original structures, so as to effectively solve the signal.
