Generalizations of the theory to include nonlinear effects have been performed by Hall et al. [19], Agarwal [28], Schenzle et al. [29], and Shirley [30]. Whittaker and Bjorklund [31] have extended the ... WebThe term “quadrature modulation” refers to modulation that is based on the summation of two signals that are in quadrature. In other words, it is I/Q-signal-based modulation. We’ll use QPSK as an example of how quadrature modulation works, and in the process we’ll see how amplitude modulation of I/Q signals can produce phase shifts beyond 90°.

WebPhase modulation is calculated by adding the baseband signal to the argument of a sine or cosine function that represents the carrier. The modulation index makes the phase variations more or less sensitive to the behavior of the baseband signal. The frequency-domain effects of phase modulation are similar to those of frequency modulation.

WebIn a nutshell, for FM signals, the frequency of the signal varies based on the voltage level coming in. So a high voltage gives a high frequency, and vice versa. With AM, the frequency stays the same, but the amplitude goes high or low depending on the input voltage.
