As practical signals are time limited, they have infinite frequency bandwidth. Sampling of such signals lead to aliasing. To avoid aliasing, an anti-aliasing filter is used
Four signals g1(t), g2(t), g3(t) and g4(t) are to be multiplexed and transmitted g1(t) and g4(t) have a bandwidth of 4 kHz, and the remaining two signals have bandwidth of 8 kHz. Each sample requires 8 bit for encoding. What is the minimum transmission bit rate of the system?
Consider a Binary Symmetric Channel (BBC) with probability of error being p. To transmit a bit, say 1, we transmit a sequence of three 1s. The receiver will interpret the received sequence to represent 1 if at least two bits are 1. The probability that the transmitted bit will be received in error is
