Detailed Solution
Download Solution PDF- PCM (Pulse Code Modulation) is a digital scheme for transmitting analog data.
- The amplitude of an analog signal can take any value over a continuous range, i.e. it can take on infinite values.
- But, digital signal amplitude can take on finite values.
- Analog signals can be converted into digital by sampling and quantizing.
Advantages of PCM:
- Encoding is possible in PCM.
- Very high noise immunity, i.e. better performance in the presence of noise.
- Convenient for long-distance communication.
- Good signal to noise ratio.
Disadvantage of PCM:
- The circuitry is complex.
- It requires a large bandwidth.
- Synchronization is required between transmitter and receiver.
