    PPM Modulation and Demodulation Trainer

    Nvis 6577

    Product Description

    PPM Modulation and Demodulation Trainer Nvis 6577 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 unmodulated 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

    Nvis 6577, PPM Modulation and Demodulation Trainer is an ideal platform to enhance education, training, skills & development amongs our young minds.
