How to Evaluate Maximum Amplitude?

Maximum Amplitude evaluator uses Maximum Amplitude of AM Wave = Amplitude of Carrier Signal*(1+Modulation Index^2) to evaluate the Maximum Amplitude of AM Wave, Maximum amplitude is the greatest amplitude of the modulating wave. It is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. Maximum Amplitude of AM Wave is denoted by A_max symbol.

How to evaluate Maximum Amplitude using this online evaluator? To use this online evaluator for Maximum Amplitude, enter Amplitude of Carrier Signal (A_c) & Modulation Index (μ) and hit the calculate button.

FAQs on Maximum Amplitude

What is the formula to find Maximum Amplitude?

The formula of Maximum Amplitude is expressed as Maximum Amplitude of AM Wave = Amplitude of Carrier Signal*(1+Modulation Index^2). Here is an example- 19.2032 = 17*(1+0.36^2).

How to calculate Maximum Amplitude?

With Amplitude of Carrier Signal (A_c) & Modulation Index (μ) we can find Maximum Amplitude using the formula - Maximum Amplitude of AM Wave = Amplitude of Carrier Signal*(1+Modulation Index^2).

Can the Maximum Amplitude be negative?

No, the Maximum Amplitude, measured in Electric Potential cannot be negative.

Which unit is used to measure Maximum Amplitude?

Maximum Amplitude is usually measured using the Volt[V] for Electric Potential. Millivolt[V], Microvolt[V], Nanovolt[V] are the few other units in which Maximum Amplitude can be measured.
