Explain in details with all figures and equations the modulation index of Amplitude Modulation (AM) and then show the AM wave when the modulation index > 1 , modulation index < 1 and modulation index =1.choose the best case and why. 1-draw the three cases. 2-write an example.

What is modulation? Why is it done? Describe one of the types of amplitude modulation

IX. A carrier signal is amplitude modulated by a sinewave. The resulting AM waveform is shown below. a) b) c) d) 5.5V- 2V What is the percentage of modulation? What is the amplitude of the carrier signal? To achieve 75 percent modulation, what amplitude of the modulating signal is needed? Calculate the effective voltage of the AM signal

Why is a high percentage of modulation desirable?

Describe the characteristics and use cases of different modulation techniques, such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).

What is the graph of the FM and PM magnitude spectrum with sine modulation?

I need the answer quickly

please answer with detail solutions with formula

What are specifications of Analog modulation techniques?
