DPSK Modulation & Demodulation SB-227

Product Category :  Digital Communication Lab Trainer  (Series : 200-B)
Product Name : DPSK Modulation &  Demodulation
Model No.: SB-227
Product Details  :

• DPSK Modulation: The circuit uses logic gates, Delay circuit, PSK modulator using IC 1496 wired with RC components to provide the DPSK output for the applied 8 bit Data input. The 8 bit digital data input and clock input is applied to logical delayed circuit to provide the differential data input signal to PSK modulator with the carrier input signal to output DPSK signal. On board 8 bit digital Data and Clock signal generator. Sine wave carrier signal generators (1No) with variable frequency upto 100KHz and 10Vpp amplitude. facility to change the digital data input bits and carrier input. maximum modulating Data input frequency 5KHz, maximum carrier input frequency 100KHz.

• DPSK Demodulation: The circuit uses PSK demodulator using IC 1496, logic gates, Delay circuit wired with RC components to provide the demodulated digital data output with minimum noise for the applied DPSK input. Digital Data input 8 bit, carrier reference input, maximum carrier input frequency 100KHz, DPSK Detector bandwidth upto 2KHz, Discrete level circuit, Built-in fixed DC +12V/+5V/1A Power supply and maximum test point.
