How to Evaluate Minimum Amplitude?

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

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

FAQs on Minimum Amplitude

What is the formula to find Minimum Amplitude?

The formula of Minimum Amplitude is expressed as Minimum Amplitude of AM Wave = Amplitude of Carrier Signal*(1-Modulation Index^2). Here is an example- 14.7968 = 17*(1-0.36^2).

How to calculate Minimum Amplitude?

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

Can the Minimum Amplitude be negative?

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

Which unit is used to measure Minimum Amplitude?

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