FORMER OF A SINGLE LOGICAL PULSE

The former of a single logical pulse relates to automatics and computer engineering. The invention may be used for processing of pulses (broken trough switch contact bounces) to a single pulse. The beginning and the ending of pulse are coincided with beginning of direct or indirect switching of electric circuit of contact pair. The former includes two starting circuits. The start inputs of starting circuits, the direct input of the first starting circuit, and the inverting input of the second starting circuit are connected to the device input. Reset input of the second starting circuit is connected with inverting input of the first starting circuit. The first input of AND element is linked with device input, the second input is linked with the inverting output of the second starting circuit and reset input of the first starting circuit. The first input of OR element is linked with output of AND element, the second input - with direct input of the first starting circuit, the output is connected to device output. The technical result consists in simplification of the circuit.
