An amplifier has a spectrally pure sine wave input of 50 mV. It has a voltage gain of 60. A spectrum analyzer shows harmonic of 0.035V, 0.027V,0,019V,0.011V, and 0.005V. Calculate the total harmonic...

a 1MHz 40 Vpeak carrier is modulated by a 5-KHz intelligence signal so that m=0.7. This AM signal is fed to a 50 ohm. Calculate the power of each spectral component fe to the antenna?

An modulated carrier is 300Vp-p. Calculate %m when its maximum p-p value reached (400,500, and 600) V?
