Question
Solution
Answer: True
Raised cosine (RC) pulses are indeed designed to satisfy the Nyquist criterion for zero inter-symbol interference (ISI) at sampling intervals. They are derived from Sinc pulses, which are used in pulse shaping in communication systems. The raised cosine filter effectively limits the bandwidth of the transmission while meeting the Nyquist criterion. It provides an optimal solution that allows for controlled roll-off, offering a trade-off between bandwidth and performance. Thus, the statement that raised cosine pulses satisfy the Nyquist criterion of zero-ISI at sampling intervals and are derived from Sinc pulses is true.
