Product Description
TechBooks are compact and user friendly learning platforms to provide a modern, portable, comprehensive and practical way to learn Technology. Each TechBook is provided with detailed Multimedia learning material which covers basic theory, step by step procedure to conduct the experiment and other useful information.
Pulse code modulation and Transmitter TechBook demonstrates Pulse Code Modulation Technique which is most widely used in digital modulation system. Since analog modulation system is most prone to noise present in the channel and receiver, the digital modulation system is used because it is less sensitive to noise. The basis of digital modulation systems lies on pulse code modulation i.e. a particular characteristic of the pulse is varied in accordance with the information signal. In PCM system the amplitude of the sampled waveform at definite time intervals is represented as a binary code.
