Hello,
Analog Signal
- An analog signal is a continuous wave that changes over a period of time, it has no fixed range and is described by amplitude, period or frequency and phase.Human voice is an example of this.
- Represented by a sine wave, this is more prone to distortion and transmit data in the form of waves.
Digital Signal
- It's a discrete wave that carries information in binary form, it has finite number and is described by bit rate and bit intervals.
- The signals that are used for transmission in a computer are digital signal.
- Represented by square waves, this is less prone to distortion.
