There is a great difference between discharge period and pulse. Pulse width: it is the duration of high level. Pulse circuit: It is a circuit that generates, shapes and transforms pulse waveforms. Pulse wave: it is a signal waveform generated in the form of impact. Many people mistake the pulse for a strange substance. They think it can be used as the energy of large machines. In fact, this idea is ridiculous. So there is a big difference between discharge period and pulse.
