Objective:

• 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. 

Technical Specification :

• In built DC regulated Power Supply + 12 V, + 5V / 300mA

• On board Carrier Signal Generator

Frequency : 16 Khz                            Amplitude : 5 Vpp Aprox

• On board Sine Wave Generator

Frequency : 300 Khz                            Amplitude : 0-4 Vpp Aprox.

• Modulation using LM 311 , updown counter 74193 and digital to analogue converter IC DAC 0800

• Demodulation using low pass filter.

• Glass Epoxy PCB used as front panel. 

Optional Accessories :

• Dual Trace CRO 20MHz
