$($D$)$ Choices a$,$ b$,$ d$,$ f$,$ g and j are true.

A $5$ term approximation of average Power using Parseval's Theorem is:

$($E$)P=2^2+2{\displaystyle \underset{n=1}{\overset{5}{}}}|\frac{1}{jn}{|}^2$

$($F$)$ The signal can be written as $x(t)=-0\mathrm{.}5t+1$ in $0t4$

G$)$ None of the above

$($H$)$ Choices a$,$ c$,$ e$,$ f$,$ h and iare true.

The exponential Fourier Series coefficient $C_n$ is $C_n=\frac{2}{jn}$
