Sharma's book explains that analog systems have several limitations, including susceptibility to noise and interference, limited bandwidth, and low signal-to-noise ratio (SNR). Additionally, analog systems are prone to degradation of the signal quality during transmission, which can result in a loss of information.
Communication systems form the backbone of modern technology, enabling everything from voice calls and radio broadcasts to high-speed internet and video streaming. Sanjay Sharma’s well-regarded textbook on communication systems presents clear explanations of both analog and digital techniques. This blog post distills core concepts and practical insights from that material into an approachable guide for students, engineers, and curious readers.
Digital communication systems transmit information through discrete signals, which represent binary data (0s and 1s). These signals are more resistant to noise and interference, making them more reliable than analog signals. Digital systems are widely used in applications such as:
