FAQs of TDM Pulse Code Modulation Transmitter Trainer:

Q: How does the TDM PCM Transmitter Trainer demonstrate communication principles?

A: The trainer uses two analog input channels with selectable sampling frequencies, allowing you to observe how signals are sampled, encoded using PCM, and multiplexed via TDM. With LED indicators and multiple test points, you can monitor each stage, making the understanding of these principles direct and hands-on.

Q: What types of analog signals can be input into the trainer?

A: The device accepts both sine and square wave generator inputs through its dedicated analog channels, enabling you to evaluate how different waveforms are processed during PCM and TDM experiments.

Q: When can the different sampling frequencies be selected?

A: You can choose your preferred sampling frequency (typically 8 kHz or higher) before running an experiment, tailoring the demonstration to specific curriculum requirements or experimental objectives.

Q: Where are the test points located, and what purpose do they serve?

A: Test points are strategically positioned throughout the front panel to provide you with easy access for signal monitoring and measurement at different stages, including the input, sampled, encoded, and multiplexed outputs.

Q: What is the process for performing a PCM and TDM experiment using this trainer?

A: First, connect the supplied patch cords as per the experiment setup diagram. Select your input signals and sampling frequency, then use the sample and hold, quantizer, and encoder circuits to process the signals. Observe the combined PCM and TDM output at the test points, using LED indications for real-time status feedback.

Q: How is the trainer beneficial for educational and laboratory usage?

A: By providing clear, practical demonstrations of digital communication processes and easy monitoring at multiple stages, the trainer enhances the learning experience, reinforcing theoretical knowledge with real-world experimentation.
