To vary or inflect in a natural, customary, or musical manner; as, the organs of speech modulate the voice in reading or speaking.
To alter the amplitude, frequency, phase, or intensity of (the carrier wave of a radio signal) at intervals, so as to represent information to be conveyed by the signal; -- a technique used to convey information by means of radio waves transmitted by one electronic device and received by another.
To vary, or control, the frequency, phase, or amplitude of an electromagnetic wave or other variable.
is a method in which a signal to be transmitted is mixed with a high frequency carrier signal .
placing information onto a higher frequency carrier by means of varying the frequency, amplitude, or phase adjustment.
To adjust or adapt to a certain proportion. To vary the frequency, amplitude, phase, or other characteristic of waves).
of one's speech, varying the pitch
To vary the amplitude, frequency or phase of a video signal.
To vary the amplitude, frequency or phase of a radio frequency wave in accordance with the information to be conveyed.
To mix a voice or data signal onto a carrier for transmission in a communications network.
The changing of the parameter of a video signal's frequency or amplitude.
vary the brightness, saturation, and hue of an image
To change or vary some parameter such as varying the amplitude of a signal for amplitude modulation or the frequency of a signal for frequency modulation. A modulator is the circuit that modulates the signal.
To vary the carrier wave in some way to transmit information over that carrier wave.
To vary the amplitude, frequency or phase of a wave by impressing one wave on another wave of constant properties.
To vary flow rate and/or pressure drop by changing the restriction to flow in response to an input signal. Effect of damper closure positioning to vary flue gas flow rate, flow velocity or pressure; the action of damper and damper controls to maintain a pre-set series of flow parameters such as pressure or temperature.
To change or vary some parameter such as varying the amplitude of a signal for amplitude modulation or the frequency of a signal for frequency modulation. The circuit which modulates the signal is called a modulator.
To vary the frequency, amplitude, or phase of an electromagnetic wave.
To alter a carrier frequency. Modulating a signal is the standard way of sending information on wires or via radio. AM, or amplitude modulation, is a scheme where the strength (amplitude) is changed to encode information. FM, or frequency modulation, alters the frequency of the carrier slightly to represent information. Radios use an analog carrier, and computers use a digital wave.
To blend data into a carrier signal . At the receiving side, a device demodulates the signals by separating the constant carrier signals from the variable data signals. For example, radio uses two types of modulation - amplitude modulation (AM) and frequency modulation (FM) - to mix audio signals with an AM or FM carrier signal. A modem modulates data by converting it to audible tones that can be transmitted on a telephone wire, and demodulates received signals to get the data.
To change the frequency, phase, or amplitude of a carrier wave. A modulator is a device that modulates.
To change into an analog signal. 9.28
Varying the characteristics of a wave in accordance with another wave or signal, usually to make user equipment signals compatible with communication facilities. Contrast with demodulate.
