A computer outputs binary data at the rate of 50 kbps that is transmitted using a base band binary PAM system, which is designed to have a raised cosine pulse spectrum. Find the transmission bandwidth required for roll off factor $\alpha=0.4$. ( $\mathbf{1 0} \boldsymbol{\times} \mathbf{4} \boldsymbol{=} \mathbf{4 0}$ Marks) Answer any two questions from each Module. Each question carries $\mathbf{1 0}$ Marks.

Explanation

The roll-off factor α determines the bandwidth of the transmitted signal. A higher roll-off factor results in a wider bandwidth.
