Nyquist Criterion

Key focus: As per Nyquist ISI criterion, to achieve zero intersymbol interference (ISI), samples must have only one non-zero value at each sampling instant. Consider an equivalent baseband communication system model with baud rate $latex F_{sym}=1/T_{sym}$ ($latex T_{sym}$ is the symbol period) shown in Figure 1, where the transmitter, channel and the receiver are represented … Read more
