The process of changing some charactersticsamplitudefreqencyphase etcof a carrier by the signal audio or video is called modulationmodulation means modificationvariation or changingthat means we modify the carrier wave according to the signal in modulationIn wireless transmission modulation is neccessory for sending datas to the long distances and due to the modulation transmission with out. The signal output from a demodulator may represent sound images or binary data.

How to use modulate in a sentence.

What does it mean to modulate a signal. In other words it means to vary some characteristic of a signal in an experiment. The concepts of Amplitude Modulation modulation and demodulation along with their differences are explained below. There are three types of Modulation.

We call the signal being modulated the carrier and the signal doing the changing the modulator. In telecommunications modulation is the process of conveying a message signal for example a digital bit stream or an analog audio signal inside another signal that can be. Her mood changes in accordance with the weather.

We can talk video chat and text anyone on this planet. RF signals are among the highest frequency signals and are useful in carrying information over large distances. In the earlier days of communications the necessary bandwidth for transmission of signals was not wide and even they do not hold the ability to reduce the interference signals.

The supermarkets selection of vegetables varies according to the season. Amplitude Modulation is not only the approach of modulating the signal but there also exist many other kinds of modulation techniques. Modulate definition to regulate by or adjust to a certain measure or proportion.

Modulation the process in which the carrier signal is varied according to the information bearing signal also called the modulating signal. Demodulation is extracting the original information-bearing signal from a carrier wave. To vary the amplitude frequency or some other characteristic of a signal or power source.

Modulate - vary the frequency amplitude phase or other characteristic of electromagnetic waves vary alter change - become different in some particular way without permanently losing ones or its former characteristics or essence. If the modulation signal amplitude is too great any decent frequency modulator will limit the signal so that it cant push the bandwidth of the modulated signal too wide in the frequency spectrum. Information and translations of modulation in the most comprehensive dictionary definitions resource on the web.

Frequency Modulation is one of the types of modulation. Modulation is like hiding a code inside the carrier wave. A carrier signal is one with a steady waveform -- constant height or amplitude and frequency.

These terms are traditionally used in. What does keying mean in the context of signals and modulation. See also amplitude modulation frequency modulation.

This process of imposing an input signal onto a carrier wave is called modulation. Modulate definition is - to tune to a key or pitch. Frequency-division multiplexing FDM in which CW modulation eg frequency modulation is used to translate each message signal to reside inside a specific frequency slot inside the passband of the channel by assigning it a distinct carrier frequency.

There are many types of modulation so there are many types of demodulators. A demodulator is an electronic circuit that is used to recover the information content from the modulated carrier wave. Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal.

The word modulate really just means to instantaneously change some property of a signal waveform using a different waveform. The term modulate means to exert a modifying or controlling influence on the state of something. What does modulation mean.

Two signals are involved in this process. In effect the modulating signal becomes clipped. For modulating the signal what we need is an.

The communication system uses a very clever technique called Modulation to increase the reach of the signals. This reduces the losses caused during the transmission of waves over a long range and the distance traveled by the wave can be greatly increased. The process of modulating the signal means mixing the signal with another wave of a higher frequency.

In other words modulation changes the shape of a carrier wave to somehow encode the speech or data information that we were interested in carrying. Something that unlocks a door or a password but I have no idea what does the verb keying mean in this specific context of modulation. The term modulation is a noun which refers to the process or the act of modulating.

During modulation some characteristics it can be amplitude frequency or phase is varied in accordance with the original information-bearing signal that has to be transmitted. Modulation is a process by which some characteristics of high frequency carrier signal is varied in accordance with the instantaneous value of the modulating signal. When one signal waveform modulates another it changes a property of the signal being modulated.

I know what a key is. Over modulation isnt really of any significance to FM systems unlike AM. The process of varying the RF carrier wave in accordance with the information in a low-frequency signal.

Modulation is defined as the process of superimposing a low-frequency signal on a high-frequency carrier signal.
