A message signal m (t) = cos 200071 + 2 cos 4000zi

A message signal m (t) = cos 200071 + 2 cos 4000zi modulates the carrier c (1) = 100 cos 27 fet, where fe = 1 MHz to produce the DSB signal m (t) c (t). 1. Determine the expression for the upper-sideband (USB) signal. 2. Determine and sketch the spectrum of the USB signal.
