The ETB-222 DPSK Modulation and Demodulation Trainer is designed for in-depth study and analysis of Differential Phase Shift Keying (DPSK), a widely used digital modulation technique. DPSK encodes data by shifting the phase of the carrier signal relative to the previous bit, making it more resilient to phase ambiguity in transmission. This trainer provides a practical platform for understanding the modulation and demodulation principles involved in DPSK systems. It includes all essential circuitry such as data input generation, DPSK modulator, phase comparator, and demodulator with clear test points for waveform observation using an oscilloscope.
