Do You Know What Is Delta Modulation And Explain Its Features?

Answer»

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.
