While differentiating signals we need to consider two
parameters: Amplitude and time.

For Discrete signals the amplitude is continuous but time
is discrete. Ex: PAM

Fof Digital signals the amplitude and time both are
discrete i.e., discontinuous. Ex: PCM

For Analog signals both amplitude and time are continuous.
Ex: Sine wave, AM etc.
