DELTA MODULATION & DEMODULATION

k15

 

Objectives

  • To introduce several basic concepts related to Delta Modulation (DM).
  • To study the hardware implementation of Delta Modulation.
  • A hardware circuit for DM is built so that the DM waveforms can be observed on an oscilloscope.
  • Delta Modulation is a process of modulation where a train of fixed width pulses is transmitted, whose polarity indicates whether the demodulator output should rise or fall at each pulse. The output is caused to rise or fall by a fixed step height at each pulse.

    Features of the Trainer

    • Delta Modulation is a process of modulation where a train of fixed-width pulses is transmitted, whose polarity indicates whether the demodulator output should rise or fall at each pulse. The output is caused to rise or fall by a fixed step height at each pulse.
