40690 PAM Modulation and Demodulation Trainer is a useful training product for the students to help them understand the concept of Modulation and Demodulation. Pulse Amplitude Modulation is an effective technique used to transmit the information signal over a long distance without any distortion in it. PAM is a form of signal modulation where the message information is encoded in the Amplitude of a series of signal pulses. Pulse Amplitude Modulation is a scheme, which alters the amplitude of regularly spaced rectangular pulses in accordance with the instantaneous values of a continuous message signal.
