What does a pulse signal mean? What are the common pulse waveforms? What are the differences?

The pulse signal is a discrete signal with various shapes. Compared with ordinary analog signals (such as sine waves), the waveforms are discontinuous on the time axis (there are obvious intervals between waveforms) ) but having a certain periodicity is its characteristic.

Common pulse waves include rectangular waves, sawtooth waves, triangle waves, spike waves, and step waves.

The pulse signal is expressed on the plane coordinates as a curve with countless breakpoints, which means that the limit of some points in the periodicity does not exist, such as sawtooth waves and digital circuits used in computers. signal, 0, 1.

Pulse signals, that is, signals like pulse beats, are intermittent signals compared to DC. If we use water flow to describe them, DC means keeping the faucet open and water flowing, while pulse means constantly turning the faucet on and off. Create a water pulse.

Principle

The so-called pulse signal is expressed on the plane coordinates as a curve with countless breakpoints, which means that the limit of the point does not exist in some periodic places, such as sawtooth waves. , there are also signals 0,1 of digital circuits used in computers. Pulse signals, that is, signals like pulse beats, are compared to DC, intermittent signals. If we use water flow to describe it, DC means keeping the faucet open and flowing water, while pulse means constantly turning the faucet on and off to form water pulses.
