A memory module - is just another name for a memory chip.
Amplitude Modulation.
Amplitude Modulation
Amplitude Modulation
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
am is amplitude modulation, fm, frequency modulation
FM means frequency modulation, and AM means amplitude modulation.
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
For a radio, it would mean "amplitude modulation." For time, it would mean "ante meridian."
Amplitude Modulation, the method of sending information through radio frequencies.
AM - Amplitude Modulation FM - Frequency Modulation
The depth of modulation index refers to the extent to which a carrier signal is varied by a modulating signal in amplitude modulation (AM). It is typically expressed as a percentage and indicates how much the amplitude of the carrier wave changes in response to the modulating signal. A modulation index of 100% means full modulation, where the carrier's amplitude varies completely with the modulating signal. Values above 100% can lead to distortion and over-modulation, impacting the quality of the transmitted signal.
