Assume a binary bit stream is to be modulated on an RF canier.lfthe baseband bit stream has a

data rate of $1$ Megabit per second, then:

$($a$)$ What is the first$-$zero crossing bandwidth of the RF spectrum if simple rectangular pulses

are used, assuming BPSK is used?

$($b$)$ What is the absolute bandwidth of the RF spectrum if raised cosine rolloff pulses are used,

for a $=1?$ Assume BPSK is used.Problems $351$

$($c$)$ What is the absolute bandwidth of the RF spectrwn if raised cosine rolloff pulses are used,

for a $=1/3?$ Assume BPSK is used.

$($d$)$ If a timing jitter of $1$o$-6$ seconds exists at the receiver and raised cosine rolloff pulses are

used, will the detector experience intersymbol interference from the adjacent symbols?

Explain.
