PPM MODULATION AND DEMODULATION TRAINER
PPM Modulation and Demodulation Trainer: MTBE-51
PPM Modulation and Demodulation Trainer is a very prominent training product designed for students to elucidate them the concept of Modulation and Demodulation. PPM is a method of encoding information in a signal by varying the position of pulses. The undulated signal consists of a continuous train of pulses of constant frequency, duration and amplitude. During modulation the pulse positions are changed to reflect the information being encoded the amplitude and width of the pulse is kept constant in the system. PPM has the advantage of requiring constant transmitter power since the pulses are of constant amplitude and duration. It is widely used but has the disadvantage of depending on transmitter-receiver synchronization.
