Frequency Division Multiplexer/Demultiplexer Trainer
The 7511 Frequency Division Multiplexer/Demultiplexer trainer is part of an analogue communication range which provides all the necessary inputs, test points and connections for experimentation. The 7511 demonstrates FDM techniques by transmitting a single communication line through two different modulated inputs.
Key Features
- Two variable modulating (sinusoidal) input channels with provision of voice inputs
- Two DSBSC modulators for frequency band translation of two test signals
- Two Carrier Generators
- Two Sets of Audio input Amplifier
- One adder/transmission Amplifier
- Two Demodulators
- Two low pass filters for smooth output
