Question

Station USAECE is at 950 on your AM dial and will broadcast from Shelby Hall. We want to be able to receive the signal 50 miles away with radio receivers that require 30 uwatts of sideband power. Assume that the signal loss is given by the wavelength/ We will use a sinusoidal test signal (Tone signal) at 1 KHz and 85% modulation. where d is the distant in meters amd A is (20 points) How much total power must be transmitted? a. b. (20 points) Write an expression of the transmitted signal (time domain), with numerical values for all constants (except ) (10 points) How much total transmitted power would be required if DSB-SC modulation was used instead? c.
