2.16 Suppose you want to implement an SRRC pulse shape. The pulse shape is continuous and the pulse shape theoretically lasts for-

ever. You generate samples of the pulse in the time domain and truncate the pulse to some number of samples. Suppose you generated

eight samples per seconds where I is the time between pulses. You can assume T = 1. You can use MATLAB". Do the following for

a = 0.05,0.15,0.25.

(a) Determine how many samples you need if the maximum sample you ignore is 40 dB down relative to the peak sample. That is, the

amplitude of any sample you ignore must be 0.01 times as small as the peak sample.

(b) Determine the frequency content of the signal (plot the frequency content in dB) versus f.
