Answer / srikanta
Digital signals have two different state either 1(high) or
0(low) continuously but discreet signals have different
value at discreet time intervals

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.

Answer / hardik
Digital Signals are quantized. (have a value from a specific set of values)
Discrete Signals are not quantized, and can have any values. but they are not continuous in time like digital signals.
