Problem $3$

Determine the FM Bandwidth required to transmit a Carrier Signal modulated with a $5$ kHz signal and the carrier has a maximum deviation of $10$ kHz $.$ Use the attached Table $5-2.$ Plot the Frequency Spectrum over the Bandwidth.

Problem $4$

Given the following FM Signal: applied to a $100-$Ohm Antenna; find the following: $($a$)$ Carrier Frequency, $f_c$; $($b$)$ Transmitted Power, $P_c$; $($c$)$ Modulation$-$Index, $m_f$; $($d$)$ Intelligence Signal Frequency, $f_i$; $($e$)$ Bandwidth, BW; and $($ f $)$ In each of the Sideband$($s$)$ predicted by Table $5-2.$

Problem $5$

In an attempt to minimize the effect of the low gain of the highest frequencies the FM Signal, two $(2)$ two techniques are used; one is applied in the Transmitter and the other in the Receiver:

$($A$)$ Name these techniques, and state where each is used.

$($B$)$ Describe at least one of these techniques and show the simple circuit use to perform the operation described.
