WebBinary Symmetric Channel (BSC) Let's consider a noisy disk drive that transmits each bit correctly with probability (1 - f) and incorrectly with probability f. This model communication channel is known as the binary symmetric channel. As an example, let's imagine that f = 0.1, that is, ten per cent of the bits are flipped.
