Product Code : SCL-CE-12513
Indian Lab Suppliers supplies the 4-Channel TDM-PCM Transmitter and Receiver (Product ID: 12513), part of the Communication Equipment range under Laboratory equipment, a compact board combining Time Division Multiplexing (TDM) with Pulse Code Modulation (PCM) transmitter and receiver circuits, switchable between 2-channel and 4-channel operation on the same board.
Quick Answer
This trainer lets students study Time Division Multiplexing and Demultiplexing with Pulse Code Modulation in both 2-channel and 4-channel configurations, using four dedicated on-board DDS signal generators, one per channel. It is related to our standalone TDM Pulse Code Modulation and Transmitter Trainer (Product ID 12491) and TDM Pulse Code Modulation Receiver Trainer (Product ID 12492), and part of our broader Digital Communication Trainer family (Product ID 12489).
Key Features
Modulator and demodulator on the same board · four dedicated on-board DDS signal generators, one per channel, for standard and arbitrary signals · selectable sampling frequencies · four on-board 2nd-order Butterworth low-pass filters · SMD LED indicators · compact, lightweight, book-like form factor for hands-on learning.

Experiments
Study of Time Division Multiplexing and Demultiplexing with Pulse Code Modulation; 2-channel and 4-channel Time Division Multiplexing; sample-and-hold output at different channels while varying the sampling and signal frequency; parallel-to-serial conversion by varying the line-speed clock at different channels; single-bit PCM output at different line-speed clock settings across channels; single-bit multiplexed PCM output at the modulator side; single-bit demultiplexed PCM output at the demodulator side; Pulse Code Demodulation at different channels; serial-to-parallel conversion at the demodulator; and analyzing the final demodulated output with the 2nd-order low-pass Butterworth filter.
Where This Is Used
This 4-Channel TDM-PCM Transmitter and Receiver is used in electronics and communication engineering education to teach Time Division Multiplexing and Pulse Code Modulation fundamentals in a multi-channel context, complementing our broader Electronics Lab Equipment and Engineering Lab Equipment ranges.
Why Buy from Indian Lab Suppliers
Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this 4-Channel TDM-PCM Transmitter and Receiver alongside its broader Communication Equipment catalog, with documentation such as a Certificate of Origin available on request for institutional and export orders.
Frequently Asked Questions
Does this board support both 2-channel and 4-channel TDM-PCM?
Yes, both configurations are supported on the same board, with a dedicated DDS signal generator for each of the four channels.
How does this differ from your standalone TDM-PCM Transmitter and Receiver?
This unit combines transmitter and receiver functions on one board and adds 4-channel operation, while our separate TDM Pulse Code Modulation and Transmitter Trainer (Product ID 12491) and TDM Pulse Code Modulation Receiver Trainer (Product ID 12492) are dedicated 2-channel units on individual boards.
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.
