Magnitude of Modulating Signal

Go Modulating Signal Magnitude = (Maximum Amplitude of AM Wave-Minimum Amplitude of AM Wave)/2

Maximum Amplitude of AM Wave

Go Maximum Amplitude of AM Wave = Amplitude of Carrier Signal*(1+Modulation Index^2)

Amplitude Sensitivity of Modulator

Go Amplitude Sensitivity of Modulator = 1/Amplitude of Carrier Signal

Bandwidth of AM wave

Go Bandwidth of AM Wave = 2*Maximum Frequency

Minimum Amplitude of AM Wave Formula

Minimum Amplitude of AM Wave = Amplitude of Carrier Signal*(1-Modulation Index^2)
A_min = A_c*(1-μ^2)

How to calculate Minimum Amplitude when Maximum Amplitude and Modulation Index values are given?

In case when Maximum Amplitude and Modulation Index values are given we can obtain Minimum Amplitude by rearranging the given formula below;
μ = Amax+Amin / Amax−Amin
This gives the value of Minimum Amplitude of AM Wave(Amin).
