Problem $2$

Given the following equation for the signal from an AM Transmission communicationssystem:

$e(t)=10000$Sin$(2{10}^{6}t)+5000\{Cos[(2{10}^{6}t)+(2{10}^{4}t)]+$Cos$[(2{10}^{6}t)-(2{10}^{4}t)]\}$

$($A$)$Name each parameter in the signal equation for $e(t).$

$($B$)$ What is the frequency of the modulated carrier, $e(t)?$ Sketch its waveform.

$($C$)$What is the frequency of the intelligence signal? Sketch its waveform.
