A shaper of meander-type pulses with adjustable pulse width comprises two counters, each of which has a clock input, parallel load inputs, asynchronous reset inputs; a circuit comprising in series connected resistor and capacitor, a start/stop device comprising a synchronous flip-flop having an asynchronous reset input, first and second two-input elements AND; a three-input element OR. Instead of typical binary counters, counters made on shift registers having two series inputs, two standard conditions inputs, according a circuit of maximal width sequence generator, i.e. has a two-input modulo 2 addition inverting element. |
