Claims

29 is connected to the input busbars, and the output is with the second trigger input, the auxiliary output of the output pulse generator is connected to the second input of the counter and the third trigger input. The drawing shows a block diagram of a signal shaping device. The device consists of the generator 1 of the reference frequency, the trigger 2, the element 3 And, the counter 4, the multisexor 5, the driver 6 output pulses. The device works as follows. The reference frequency generator 1 sets the minimum discrete response time to input signals. The current state of counter 4, the output of which is connected to the control input of multiplexer 5, determines the switching of the corresponding input signal to the output of multiplexer 5. The number of information input of multiplexer 5 corresponds to the binary code of counter 4. The zero state of counter 4 is initial. Consequently, on BbixoA, multiplexer 5, a signal appears: when a signal appears at the first output of the device. This implements the idle mode of the device. A signal appears on the output of the 5th type LCD 5 only, trigger 2 on the leading edge of the synchronization signal switches to the one state, and unit 1 is added to the contents of counter 4, j, thus, to the output of the multiplexer 5 the next device input. the output corresponds to the switching off of the trigger 2 to the zero state, then through the element 3 And pass, just a single pulse of the clock synchronization and the device again enters the mode of waiting for the next input to change state. Thus, all inputs are sequentially resolved. The output signals are the signals from the output of the output driver and the pulses 6, the control inputs of which are connected to the output of the counter 4. The output pulse generator 6 converts the binary code of the counter 4 into a distributed no3HujioHHbm code. 8 4 The presence of signals at the outputs is determined by the state of counter 4, which varies depending on the presence of the signal at the inputs. The presence of a signal at the additional output of the output pulse generator 6 corresponds to the counter overflow code and is faulty for trigger 2 and counter 4. Thus, a multifunctional cyclogram is implemented, including standby mode, which allows control of the object (e.g. management) according to its algorithm. Compared to a multinational one, with a delayed and pulsed generator, in which each pulse counter is required for each channel, the proposed device contains only one counter, which greatly simplifies the device. Formula of signal shaping device containing a reference frequency generator, a counter and an output pulse shaper, characterized in that, in order to simplify it when implementing a multichannel mode, a multiplexer, a trigger and an And element are inputted to it, the reference frequency generator output is connected to the first inputs And the trigger, the output of which is connected to the second input of the element I, the output of which is connected to the first input of the counter, the output of which is connected to the input of the former OUT of 1–1 pulses and the second in Odom multiplexer, the first multiplexer are connected to inputs vhodn№1i tires, and the output - to the second input flip-flop, a further output of the output pulses is coupled to a second input of the counter and the third input latch.
