The Frequency Division Multiplexing / Demultiplexing Model FDMD1 is a versatile self contained stand alone unit consisting of two channel Frequency Division Multiplexer & Demultiplexer. It is useful in the study and demonstration of carrier generation, amplifier, modulation, DSBSC modulation and DSBSC demodulation. The unit is housed in an elegant cabinet with a well spread intelligently designed circuit layout on front panel. Test points are provided at various stages in the circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive instruction manual complete with theory and operating details.
