A shaper of multiphase series with adjustable number, width of pulses and number thereof in a series comprises a reversible binary countdown counter, a circuit, two synchronous D flip-flops with an asynchronous reset, first and second two-input AND elements, two OR elements, a demultiplexer. The second and third reversible binary countdown counters having a clock input, a synchronous parallel load enable input and loading data inputs, a counting mode enable input, an asynchronous reset and an overflow output, the third OR elements are introduced. |
