What is Delta modulation? Describe its features.

- A technique that converts analog to digital and digital to analog signal conversion.

- It is to transmit voice information.

- It encodes the differences between successive samples into n-bit data streams.

- The transmitted data is reduced to 1-bit data stream.

Following are the features of Delta Modulation:

- A series segments are used to approximate the analog signal.

- The approximated signal is compared with analog wave for determining the increase or decrease in relative amplitude.

- Only the increase or decrease of the signal amplitude is only sent.
