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.

MSK Modulator/ Demodulator Scientech 2116 demonstrates the basic working of Minimum Shift Keying technique. As the name suggests, MSK results in a modulation scheme which has smooth phase variations in contrast to other phase modulation schemes where the modulated signal contains abrupt phase changes. The immediate advantage of such a scheme is the reduction in modulated signal bandwidth.
