ANGLE MODULATION-a method to modulate sinusoidal wave
This PDF is about angle modulation. It includes frequency modulation -types,spectrum,phasor representation,analysis of the spectrum,power calculations etc.
Power computation of sinusoidal and non sinusoidal circuits
This file has all the necessary details about the power computation of sinusoidal and non-sinusoidal AC circuits. They are described using the Fourier series for proper understanding.
