Description

(54) THE PLAYBACK DEVICE OF W-SHULDS RECTANGULAR is connected to the inputs of the second pulse decoder, and one of the outputs of the first pulse decoder is connected to a single trigger input of the memory, and the input of the pulse output is connected to the output of the trigger trigger. The drawing shows a structural electrical circuit of the device. The device contains the first counter of 1 pulses, the second counter of 2 pulses, the generator of 3 pulses, the control trigger 4, the element NOT 5, the element AND 6, the memory trigger 7, the element OR 8 the first decoder 9 pulses, the second decoder -10 pulses, switch 11 ;. The rectangular pulse reproducing apparatus operates as follows. Consider the operation of the device in the case of applying to its input signals of duration t, and differing from nominal values by the value of t due to distortion in the communication line. The input signal, with its leading edge, translates the control trigger 4 into a single state and the potential from the output of this trigger triggers generator 3. Pulses from the generator 3 trigger counter 1 on the counting input, the counter state is decoded by the decoder 9, on which outputs the following signals are generated: the first signal delayed with respect to the leading edge of the input signal by 1/21; the second signal delayed with respect to the leading edge of the input signal by 1/2 (t «+ tj,); the third signal is delayed with respect to the leading edge of the input signal by 1/2. (t + tj); the fourth signal, delayed by reference to the first signal by. Pfth signal delayed in relation to the first signal by the value of t; the sixth signal delayed with respect to the first signal by the value of tj. Moreover, the listed signals are arranged in time so as not to cover the possible tolerance field for deviation of the input signal duration. If a device with a duration t - -3 6 t 4 t has arrived at the input of the device, + then through the element 6 for the duration of the input signal only one signal from the element 8 passed and the counter 2 will be transferred to the state 1 I. The decoder 10 decrypts the state of counter 2, and the potential from its first output prepares the mutator 11 to pass the signal from

702503 decoder 9, after the end of the input signal, the potential c / element NOT 5 opens the switch 11 and resets the signal from its output to counters 1 and 2, control trigger 4 and memory trigger 7. Memory trigger 7 is set in the decoder signal 9, to the poet at its output, a signal of duration t is generated. If the input of the device receives a signal of duration t. - t, during the time of the signal through the element AND two pulses from the element OR 8 pass and the counter 2 is set to state 2, the potential from the decoder 10 is prepared by the switch 11 for the signal from the decoder 9 to pass, after the end of the input signal the potential from the element 5 does not allow the operation of the switch 11, and its output signal, returning the device to the initial state, generates a signal with the duration tg on the memory trigger 7. If a signal with a duration tj - tj + + arrives at the input of the device, then the counter with 2 pulses from element Ib will be set to state 3, the decoder 10 with potential from its third output prepares the switch 11 to pass the signal from the decoder 9, which after the end of the input signal passes through the switch 11, will return the device to the initial state and reset the memory trigger 7 through t after it will generate a signal with duration tj on its installation in the output; Thus, the proposed device recovers the nominal duration of a signal quantized by duration. of the invention. A rectangular pulse reproducing device comprising two pulse counters, the input of the first of which is connected to the output of the pulse generator, a control trigger, an element NOT and an element AND whose inputs are connected to the input of the device, a memory trigger whose output is connected to the output of the device and an element. OR, distinguish it with the fact that, in order to expand its functionality, the first and second decoder impulses are introduced into it, the switch, the first group of inputs of which is connected to the first group of outputs pulse decoder, the second group of inputs - with the outputs of the second pulse decoder, a third - with the output of the NOT element, and the output - with the installed inputs of both pulse counters, with zero inputs of the memory trigger and control

trigger, the outputs of the first pulse counter connected to the inputs of the first pulse decoder, the outputs of the second group of which through the OR element and the element And connected to the input of the second pulse counter, the outputs of which are connected to the inputs of the second pulse decoder, and one of the outputs of the first pulse decoder connected to a single input the memory trigger, and the input of the pulse generator is connected to the output of the control trigger.
