TDM Pulse Amplitude Modulation/Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12572
Indian Lab Suppliers supplies the TDM Pulse Amplitude Modulation/Demodulation Trainer (Product ID: 12572), part of the Communication Equipment range under Laboratory equipment, a digital communication trainer demonstrating Pulse Amplitude Modulation combined with Time Division Multiplexing across four analog input channels, with onboard functional block diagrams and test points for oscilloscope visualization.
Note on naming and scope: our catalog also includes the TDM Pulse Amplitude Modulation and Demodulation Trainer (Product ID 12490); please confirm the exact model with our team. Both trainers cover TDM-PAM multiplexing/demultiplexing across four analog input channels with adjustable-amplitude onboard sine sources and a separate DC source, but the documented specifications differ — this trainer uses a 6.144 MHz crystal-controlled pulse generator with a 32 kHz/channel sampling rate, an 8 kHz channel-identification signal, PLL-based clock regeneration at the receiver and a 4th-order Butterworth low-pass filter (3.4 kHz cutoff), while Product ID 12490 is documented with an 8 MHz crystal and a three-mode (3-signal/2-signal/1-signal) transmitter-receiver communication scheme.
Quick Answer
This trainer lets students study TDM-PAM multiplexing and demultiplexing across four analog input channels, using an onboard sine wave generator (250 Hz to 2 kHz, adjustable amplitude), a separate adjustable DC source, a crystal-controlled pulse generator with per-channel sampling and channel-identification signals, PLL-based clock regeneration at the receiver, and a 4th-order Butterworth low-pass filter for signal reconstruction, with functional block diagrams and test points provided for oscilloscope-based analysis.

Frequently Asked Questions
How is this different from your TDM Pulse Amplitude Modulation and Demodulation Trainer?
The two trainers cover the same TDM-PAM technique across four channels, but with different documented hardware specifications (crystal frequency, sampling scheme and receiver design); please confirm the exact model with our team. See our TDM Pulse Amplitude Modulation and Demodulation Trainer (Product ID 12490) for the alternative model.
What filter is used to reconstruct the demultiplexed signal?
A 4th-order Butterworth low-pass filter with a 3.4 kHz cutoff frequency is used at the receiver, following PLL-based clock regeneration.
Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
