Time Division Multiplexing Pulse Amplitude Modulation is communication system where the message signal modulates using Pulse Amplitude Modulation and multiple access is provided using Time Division Multiplexing. The message information is encoded in the amplitude of a series of signal pulses and transmitted using Time Division Multiplexing (i.e. in different time slots).
Scientech 2152 TDM PAM Transmitter and Receiver demonstrates working of communication system in various modes of operation. It is an ideal teaching aid to enhance education, training, skills & development amongs our young minds.
Scope of Learning
-
Study and analysis of 2 channel & 4 channel time division multiplexing
-
Study and analysis of sample & hold output at the different channel by varying the sampling as well as signal frequency.
-
Study and analysis of parallel to serial conversion by varying the line speed clock at the different channel.
-
Study and analysis of single bit PCM output at different line speed clock at the different channels.
-
Study and analysis of single bit multiplexed PCM output at modulator side and demodulator side
-
Study and analysis of pulse code demodulation at the different channel and perform serial to parallel conversion at the demodulator.
-
Analyze the final demodulated output with second order low pass Butterworth filter.
