WebModulation Examples Examples of linear modulation include amplitude modulation, where the modulating signal affects only the amplitude of the modulated signal (i.e., when ζ(t) is a constant ∀t (for any t)), and phase modulation (with a rectangular phase shaping function) where the modulating signal affects only the phase of the WebQAM (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. This is done by manipulating the phase and amplitude of the carrier wave.

While the bit streams we wish to transmit are inherently discrete-time, all physical media are continuous-time in nature. Hence, we need to represent the bit stream as a continuous-time signal for transmission, a process called modulation. bitter taste in throat causes
