Delta Modulation/demodulation Kit
Model No. HV-EXP1933
In Delta Modulation section the signal at time tn is compared with that at tn-1.; The output is coded into a single bit (Delta Modulation output) which controls an 8 bit updown counter.; The parallel output of the 8 bit counter is connected to an ADC which gives tn-1 amplitude level.; The Delta Modulating output is connected to an 8 bit updown counter and a DAC followed by a low pass filter to regenerate the original analog signal.; HARDWARE SPECIFICATION :; Built in DC Power Supply; Built in TTL Clock Generator; Modulating signal Generator 1KHz with variable amplitude; Delta Modulator; Delta Demodulator; Assembled in plastic Box with circuit printed on PCB with 2mm socket for test points & to see the waveforms; Set of 2mm Patch Chords & Manual..
