Q1)
Frequency of peak is 1kHz
AM FFT: middle peak about 625mv, other two are about 500, first peak at 800hz, secnod at 1khz, 3rd at 1.2khz
-27.857 left and right peak and -22.22db middle peak
change to 1.2khz just shifts it all right
change modulation to 100hz brings the right and left peaks closer together cahnge modulation to 300hz brings them further apart
AM depth brings the amplitude of the peaksa on the side down doesnt affect main peak
FM Carrier Increase Freq just shifts right
The side bands get squeezed further together
300 brings them further out
Bandwidth of 300hz Mod is 600hz Bandwidth of 500 Mod is 1kHz Bandwidth of 100 is 200Hz Bandwidth of 200 is 400Hz
