In the figure is the short pulse bundle waveform generating circuit. A2 is the comparator, which detect the positive zero crossing point, and it outputs short pulse wave strings from sin0°, and the wave string is synchronized by 74HC74. The output time of the short pulse string is provided by the external pulse generator, but this will make it not synchronize with the phase of the sine wave oscillator, so when it reaches the high LEV with the help of the short control pulse, it makes the Q point of the dual stable state multi-resonance oscillator 74HC74 in a high LEV, then analog switch DG201CJ is on and the pulse string is output by the buffer.
