The Continuous-Time Impulse Function 1/4
The basic definition of the continuous-time unit impulse function delta(t) is provided in this video. This signal is zero everywhere except at t = 0, and has the property that when integrated across zero its integral is equal to one.
We see how the impulse function can be thought of as the limit of a rectangular function of unit area as its width goes to zero and its height goes to infinity.
