(the stream of zeros and ones). this, in turn, is made into a specific type of wave that is superimposed on the carrier. read more: frequency modulation what is demodulation? demodulation is defined as extracting the original information-carrying signal from a modulated carrier wave. a ...
What is a carrier wave? Wave: Wave is a manifestation of disturbance or oscillation that propagates through space and time and is accompanied by an energy transfer without the transfer particles. Some practical applications of waves include sound and light waves. ...
To observe the effect of modulation, combine a carrier sine wave with a message signal. Plot the carrier, message, and frequency-modulated signals.Multicarrier Modulation In multicarrier modulation, the process alters characteristics of a collection of carrier sine waves by combining each with a dif...
The purpose of modulation isto impress the information on the carrier wave, which is used to carry the information to another location. In radio communication the modulated carrier is transmitted through space as a radio wave to a radio receiver. What is modulation and its significance? Modulation...
Modulation is the process of varying a carrier signal to transmit information. Demodulation is the reverse process, extracting the original information from the modulated signal.
Demodulator: decodes the signal on the receiver side. It extracts the original information-carrying signal from the modulated carrier wave. Power amplifier:used to amplify the output of the mixer to a higher power for transmission. The range of coverage increases with the efficiency of transmission...

The actual information in a modulated signal is contained in its sidebands, or frequencies added to the carrier wave, rather than in the carrier wave itself. The two most common types of modulation used in radio areamplitude modulation (AM) and frequency modulation (FM). ...
QAM (pronounced “kwom”) stands for Quadrature Amplitude Modulation. It is a way of modulating, or changing, a waveform, called a carrier wave, to encode the 1’s and 0’s that make up the data you wish to transmit across the RF (Radio Frequency) medium
