Pulse Position Modulation (PPM) Educational Trainer Kit with Demodulator Circuit

The Pulse Position Modulation and Demodulation Trainer Kit offers a complete setup to study the working of time-based pulse modulation in digital communication. It enables clear observation of the signal transition from analog input to PPM output and back to analog through demodulation. Ideal for electronics labs, it helps students grasp the principles of sampling, modulation, and filtering.
