Description
technical field [0001] The invention relates to the technical field of pulse signal generation, in particular to a pulse signal generating device. Background technique [0002] In the military and civilian fields such as electric power, communication, radar, and laser guidance, the generation of low-frequency high-precision pulse signals is a key technical difficulty, especially the generation of two microsecond-level advanced synchronization pulse signals under low-frequency conditions. Existing finished instruments And the general design circuit can not meet the requirements. [0003] DDS technology is direct digital frequency synthesis technology, which can directly generate two pulse signals. The existing DDS circuit that generates two-way pulse signals is generally composed of a reference clock, a phase accumulator, a phase delay, a waveform memory, a D / A converter and a low-pass filter. The accuracy of the pulse cycle is determined by the number of bits of the phase ...
