The Pulse Code Modulation and Demodulation Trainer from AGN Enterprises is an educational laboratory system designed for the practical study of Pulse Code Modulation (PCM), sampling, quantization, encoding, decoding, demodulation, and digital communication systems.
The trainer helps students understand how an analog information signal is converted into a digital pulse code for transmission and subsequently recovered at the receiver. It provides a practical platform for studying the complete PCM modulation and demodulation process.
Students can study the different stages of PCM, including sampling, quantization, binary encoding, digital pulse transmission, decoding, and signal reconstruction. The trainer enables learners to understand how an analog signal is represented by a sequence of binary coded pulses.
Suitable test points and output terminals allow students to observe and analyze the input, sampled, encoded, transmitted, decoded, and reconstructed signals using compatible measuring instruments.
The trainer provides a structured platform for studying both the transmitter and receiver sections of a Pulse Code Modulation system. In addition, instructors can demonstrate how an analog message signal is sampled and converted into a binary code at the transmitter and how the original information is recovered through decoding and reconstruction at the receiver.
Students can practically investigate the effect of sampling and quantization and understand the basic operation of digital communication systems based on PCM technology.
