Description

technical field [0001] The invention relates to a pulse signal generator applied in the technical field of modern measurement and control, in particular to an adjustable pulse signal generator. Background technique [0002] Pulse signals are very common in nature, such as thunder and lightning, or the instantaneous predation process of some reptiles all contain pulse information. Pulse refers to the activity that a certain physical signal returns to its original state after a period of movement. The pulse signal is a discrete signal with various shapes. Compared with ordinary analog signals (such as sine waves), the waveform between It is characterized by discontinuity in the time axis (there is a clear interval between waveforms) but has a certain periodicity. The most common pulse wave is the rectangular wave (aka square wave). Pulse signals can be used to represent information, and can also be used as a carrier, such as pulse code modulation (PCM), pulse width modulatio...
