WO1988003338A1 - Method and device for receiving frequency-modulated analog signals with digital processing - Google Patents

Abstract

The method consists in directly converting a frequency-modulated analog signal by purely digital methods into a numerical code ($g(D)N) proportional to the deviation ($g(D)f) of the signal of the intermediate frequency (f). The device for implementing the method comprises a converter (1), a comparator (3), a frequency divider (5), a pulse duration measuring unit (6), a processor (7), a signal dividing unit (8) and a generator (9) of synchronizing pulses.

15 General Detection and Amplification of Sound Signals. When installed, an additional operation is carried out: after the operation is completed, the signals are separated into components that are compatible with the left and the right.

20 The written method, however, in this way the sound signal is distorted, is caused by the normal occurrence of the accidents.

We are aware of a frequent and frequent method.

£ = £ ₀ + Δ £, where (I)

£ _ο - unmodulated frequency of the signal at the intermediate frequency; Δ £ is the signal deviation at the intermediate frequency. 35 This signal is interrupted by analogue and non-analogue communication, but after a single interconnection - 2 - it is imperative that there is no other hazardous substance (waste). Then, the received signal is processed in a digital manner in accordance with the expression:

where = 2% is the instantaneous frequency for the switch. discretization;

Τι - the transition between two neighbors, that is, the sampling;

Α-d>, Α ₂ , are the values of the code in the series of successive samples following each other. Further, the signal is retuned for processing - digital - after which, I can be used for the purpose of exploitation.

Otherwise, to learn how to do non-linear distortions and noise, use a high frequency of 4 to II MHz.

The well-known device ensures a low accuracy of measurements, caused by the small useful content in the demodulated signal. Κροome

BEST MODE FOR CARRYING OUT THE INVENTION The proposed method of using the frequency-modulated signal is 15 of the following analogue signals with the digital processors as follows. The primary frequency-analogue signal is converted to an analogue signal and converted to the following frequencies:

^£ = ^£ ο ± ^{ΔГ "} (I)

20 where £ is the unchanged frequency of the signal at the intermediate frequency; Δ £ -. signal deviation at the intermediate frequency. After this analog signal, the intermediate part is switched on at the same moment as the pulse at 25 of the same frequency, for example, on the right side. Then, the partial division of the frequency of the obtained pulses in Κ times is produced, by which we choose the division coefficient from the condition:

20 ^'The operation of the tracking part of the device, that is, there are 9 generators (Fig. 4) of synchronizing impulses is carried out by the following way. Upon entering the generator 9 from the output of the compressor 3 (Fig. Ι), a signal will be sent, which will provide a proper sequence of direct impulses, often

25th, the next circuit is equal to the intermediate frequency (fig. Ba). After processing the part of its part 27 (Fig. 4) and filter 28, the signal delivers its own self-modulation (Fig. 4). It is not connected to input 29 (Fig. 4), signals to direct

When there is a signal in the system with a pilot instead of a signal of a relatively high frequency, in the case of an interruption of operation, there are no signals at all. All of the foregoing is related to the case of an increase in regular signals, in the case of an increase in signaling, there is a significant loss of speed in the case of asynchronous signals. The family disassembling of all operational signals will remain the same, as shown in Fig. 5 and - 18 - fig. 6.

Please note that the optional signal is not available from the signal of the intermediate frequency £. The exclusion of one of the products - part 5 of the 5th product - is to perpetuate the accuracy of the deviation Δ £, to simplify the process and to compress.
