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
Is This Answer Correct ? | 69 Yes | 6 No |
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.
