Differential Pulse Code Modulation And Demodulation Trainer

Model No. HV-EXP2217

Description
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 8bit digital format using an ADC. The sampling rate is set at 2.5 Khz.The DPCM demodulator receives the serial data, converts it into 8bit parallel format. The Digital to Analog converter transforms the 8bit parallel data into analog level. Thus the output of DAC is astepped approximation of input signal. Alow pass filter is used to recover the analog signal. Practical experience on this board carries great educative value for science and engineering students.Object:To study differential pulse code modulation & demodulation.Features:The board consists of the following built-in parts : 5V D.C. at 100mA IC regulated power supply internally connected. ± 12V D.C. at 100mA IC regulated power supply internally connected. -5V D.C. to +5V D.C. Variable D.C. output. Audio Frequency Oscillator 10Hz to 100Hz for modulation. DPCM Modulator (DPCM ENCODER). DPCM Demodulator (DPCM DECODER). Adequate no. of other electronic components.
