Chapter 17, Problem 42P

(a)

To determine

Calculate the percentage of the energy in the signal at the output of the filter with the frequency range $0\le \left|\omega \right|=\alpha$, when $\alpha =a$.

(b)

To determine

Calculate the percentage of the energy in the signal at the output of the filter with the frequency range $0\le \left|\omega \right|=\alpha$, when $\alpha =\sqrt{3a}$.

(c)

To determine

Calculate the percentage of the energy in the signal at the output of the filter with the frequency range $0\le \left|\omega \right|=\alpha$, when $a=\frac{\alpha }{\sqrt{3}}$.
