For amplitude modulation, anderson college sc one just changes the height (voltage) of the sine wave analogous to changing the frequency of the sine wave for a simple case there could only be.
Am a (radio) modulation method whereby a high frequency (rf) carrier-frequency is modulated by a lower baseband signal (af) - the modulating signal. This is not an accident as phase and frequency are related; frequency is the time derivative of phase, and phase is the integral of frequency am (amplitude modulation).

Am stands for amplitude modulation this means the intelligence in conveyed by varying the amplitude, ancient african religion one of the parameters of the radio wave. In infrared photometry this is usually plished by use of a chopping secondary mirror, ammunition ballistics remington which is an example of amplitude modulation although chopping can also be used for.
The amplitude modulation following response (amfr, aka assr) is a promising tool for assessing hearing on a frequency-by-frequency basis. Varying the voltage of a carrier or a direct current in order to transmit analog or digital data amplitude modulation (am) is the oldest method of transmitting human voice.
