Description

one

The invention relates to computing and can be used to input analog radiometric signals into computers.

The purpose of the invention is to increase the speed and performance of the device.

FIG. 1 shows a block diagram of the device; in fig. 2 -; diagrams of i signals in the device.

The device for inputting information comprises an amplifier 1, an analog-digital converter 2, a generator 3, a first register 4, a counter 5, a second register 6, a switch 7, a decoder 8, a trigger 9, a first one-shot 10, a synchronization block 11, a second one-shot 12, a driver 13, element 14 OR, element 15 OR, element 16 delay.

The device works as follows.

In the initial state, counter 5 and trigger 9 are reset. At the output of the counter and the one-shot 10 from the source of the analog signal, burst of sync pulses are received, with the first pulse of the burst starting the one-pulse 10, which generates a signal with a duration slightly longer than the burst. This signal sets the pulse counting time in a burst. The falling edge of the signal of the first one-shot starts the synchronization unit 11, generating a pulse following the nearest signal of the ADC tracking. The back edge of the pulse of unit 11 triggers a single vibrator 12, generates a control signal from switch 7, which the decoder 8 gates, switch 7 switches to transmit information from the second register 6, and shaper 13 produces a signal accompanying the control word. Two of all possible conditions of the counter 5 at the output of the decoder 8 generate control signals for trigger 9, one of which is set, and the other to reset trigger 9. The signals accompanying the ADC and service word through the OR element are sent to one of the inputs of element 15, to the output of which as a result of the operation on both the tracking signals and the input resolution signal coming from the output of the flip-flop 9 is generated by sig151072

request for data transfer to a computer.

Signal accompanying the service word from the output of the imager 13, held by the delay element 16, reset counter 5, after which the device is ready to receive the next batch of pulses.

The original analog signal post10 is fed to the input of amplifier 1, to the output of which is connected an ADC 2. Generator 3 sets the sampling rate of the analog signal. The digitized signal is written to the first register 4 and transmitted through the switch 7 to the computer.

An overhead word is formed at the output of counter 5 as a result of counting the number of pulses in a packet

20 and at the end of the counting is recorded in the second register 6, from the output of which through the switch 7 is transmitted to the computer.

25 The use of the proposed device will allow to increase the speed and productivity of the processing means in comparison with the prototype, since it eliminates the need for

2Q of the signal preview by the operator in order to determine the location of the input plots, automatic selection is made from a large flow of information and input to the computer of the required signal plots, the input plots are supplied with service signs (words) allowing the processing program to identify the corresponding data array. 40
