Tenders Description & Specification for Differential Pulse Code Modulation and Demodulation Trainer

Differential Pulse Code Modulation and Demodulation Trainer

Experimental Training Board has been designed specifically to study Differential Pulse Code Modulation & Demodulation. In the basic DPCM Modulator the base band analog signal is covered into 8 bit digital format using an ADC. The sampling rate is set at 2.5 Khz.
The DPCM Demodulator receives the serial data, converts it into 8 bit parallel format. The Digital to Analog converter transforms the 8 bit parallel data into analog level. Thus the output of DAC is a stepped approximation of input signal. A low pass filter is used to recover the analog signal.
Practical experience on this board carries great educative value for Science and Engineering Students.
