Also known as: am.
AM has various meanings in the Physics category. Discover the full forms, definitions, and usage contexts of AM in Physics.
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to that of the message signal being transmitted.
PhysicsA multimeter or a multitester, also known as a VOM , is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made.
PhysicsThe maximum instantaneous value of alternating current or voltage. It can be in either a positive or negative direction. The greatest distance through which an oscillating body moves from the mid point. OR A measure of floor vibration. It is the magnitude or total distance traveled by each oscillation of the vibration. OR A measurement of the distance from highest to lowest excursion of a variable or physical motion. Often used with reference to waveforms.
