Step, Impulse, and Ramp Signals

Step, impulse, and ramp signals are the main basic continuous-time signals. They are also called singularity functions. These signals are known for discontinuities or for derivatives that are discontinuous.

Basic continuous-time signals include the unit step function, unit impulse function, and unit ramp function. These are collectively referred to as singularity functions.

Singularity functions are characterized by discontinuities or discontinuous derivatives.
