WebAug 24, 2024 · By capacity of a channel, it means the capacity of the transmission medium (wire or link). Capacity is the number of bits the transmission medium can hold. So basically there are 2 types of channels – Full duplex and half duplex. Half duplex – the transmission can happen in one direction at a time. Full duplex – the transmission can ... WebAug 27, 2024 · What is capacity of binary erasure channel? The binary symmetric channel has a channel capacity of 1 − H(p), where H ( p ) = − p log p − ( 1 − p ) log ( 1 − p ) is the Shannon entropy of a binary distribution with probabilities p and 1 − p. The erasure channel has a channel capacity p, where p is the probability that the transmitted ... scottsdale home explosion
