FDM Multiplexing - This has two DSB-SC balanced modulators and two channel OP-AMP based linear multiplexer wired as Frequency Division Multiplexer (FDM). Every DSB-SC Balanced modulator circuit has IC 1496 wired with RC components to provide the DSB-SC Balanced AM output for the applied modulating and carrier input signal. The modulating inputs are processed through two DSB-SC Balanced modulators for the applied respective carrier inputs to provide two DSB-SC outputs which is then applied as an input to linear FDM modulator circuit to output two channel frequency division multiplexed outputs. FDM Demultiplexing - This has two channel FDM Demodulator and two DSB-SC Balanced Demodulators with low pass filter wired as FDM Demultiplexer. Every DSB-SC demodulator has IC 1496 wired with RC components and filter network to provide the demodulated outputs for both channel inputs. The applied two channel FDM input is separated by FDM demodulator and then these signals are processed through DSB-SC balanced demodulators to recover the multiplexed signals. on board Sine wave (modulating & carrier) signal generators (4Nos) with variable  frequency upto 100KHz and amplitude. FDM Channels two analog, facility to control the modulating inputs and carrier inputs of both the channel, maximum modulating frequency 10KHz, maximum carrier frequency 100KHz, Bandwidth 3KHz, Built-in fixed DC ±12V/1A Power supply and maximum test points.  Objectives : To study the concept of Frequency Division Multiplexer (FDM). To study  the operation of two channel  FDM. To study the DSB-SC Balanced Modulation. To observe and note the DSB-SC outputs for the applied modulating and carrier inputs. To observe and note change in FDM output w.r.t. change in channel inputs.  To study the concept of Frequency Division Demultiplexing. To study the operation of FDM Demodulator. To study the DSB-SC Balanced Demodulation. To observe and note the demodulated outputs for the applied FDM inputs. To observe and note the change in demodulated outputs w.r.t. channel modulating inputs. Accessories Included : Set of Patch Cords, Operating Manual.
