Claude Shannon, often regarded as the father of information theory, made numerous significant contributions to the field. Claude Shannon’s contributions have had a profound impact not only on information theory and communication systems but also on diverse fields such as cryptography, digital circuit design, and artificial intelligence. He remains one of the most influential figures in the history of modern science and technology.

Introduction to Channel Capacity:

Channel capacity, as defined by Claude Shannon, represents the maximum rate at which information can be reliably transmitted over a noisy communication channel. It provides a fundamental limit on the performance of communication systems. Shannon’s channel capacity theorem establishes a theoretical upper bound on the achievable communication rate for a given channel with a specified level of noise.

Definition of Shannon’s Channel Capacity Theorem:

Shannon’s channel capacity theorem states that for a given communication channel characterized by a bandwidth \( B \) and a signal-to-noise ratio (SNR) \( \text{SNR} \), the maximum achievable data rate \( C \) (in bits per second) is given by:
