Question
A spectrum analyzer with an input impedance of 200 is used to
measure the power spectrum of an AM signal at the output of a
preamplifier circuit. The AM signal has been modulated with a
sine wave. The effective carrier power, Pc, is 750mw, and each
sideband, PusB and PLSB, is 120mW. Compute the following:
1- The total effective power Pr.
2- The peak carrier voltage, Vc-
3- The modulation index, m, and the percent modulation index.
4- The modulation voltage,Vm.
5- The lower -and upper - sideband voltages, VLSB and VUB.
6- Sketch the waveform that you would you see with an oscilloscope
if it were placed in parallel with the spectrum analyzer.
