Definition

A pulse (from latin pulsus) is a transient variation of a quantity whose value is normally constant (Encyclopedia Britannica).

Theory and Application

Pulse Shapes

Generally pulses can have arbitrary shape. In production technology, most frequently pulses of rectangular, triangular, Gaussian, or delta shape, or combinations of them are applied. It can be distinguished between single pulses and pulse trains. Figure 1 shows typical pulse shapes as well as their mathematical definitions.
