A signal is defined as a signal valued fraction of time (that convey the informational )and which, at every instant of time has a unique value

However as there now are more efficient and convenient methods of modulating a signal, its use is declining, although it will still be very many years before it is no longer used.Many of the more efficient methods of modulating signals are based around AM: single sideband and quadrature ...
This filtering stage before modulating the signal is also called pulse shaping as the data pulses are filtered out to produce a clean output signal with sharp rise and fall times, which helps in accurately determining the carrier frequency of the received signal. GFSK technique is useful and used...
PSK conveys data by modulating the carrier signal's phase and alters the sine and cosine inputs at precise times. PSK is most widely used for wireless LANs,RFIDand Bluetooth communications. The demodulator determines the phase of the received signal and translates it back to the symbol it repre...

Modulation is the use of one electrical signal to “control” a primary variable of another. For example, if an audio signal voltage is used to control the “amplitude” of a carrier signal, the result is amplitude modulation.It is important that you do not confuse “mixing” with “modulat...
Third-order intermodulation (two tones of a complex signal modulating each other) can be particularly troublesome because the distortion components can fall within the band of interest, which means they cannot be filtered away. Spectrum monitoring is another important frequency-domain measurement activit...

What is a synth modulator? In synthesis, to modulate meansto change or control. ... Here, the control signal generated by one synth component is used to cause a change in another component, and that's what modulation is all about. Whenever you hear a change in pitch, timbre, amplitude,...
