摘要

A pulse shaper with adjustable pulse duration and fixed pulse ratio equal to seventeen comprises two reversible binary counters turned to counterdown mode, each of witch having a clock input, asynchronous parallel load enable input, loading data inputs, counting mode enable input, asynchronous reset input, overflow input, a binary adder turned to subtraction of fixed value (equal to one), an inverter, first and second OR elements, a circuit comprising a synchronous D flip-flop with asynchronous reset input, first and second AND elements. A binary counter and a second counter with extended structure are incorporated. The structure is extended due to increase of bit number by four in comparison to bit number of first counter.
