AM modulation where the amplitude of the carrier does not depend Angle Modulation In this type of modulation, the frequency or phase of carrier is { Demodulation of FM signals Let fm(t) be an FM signal. fm(t) = Acos(!ct+kf Z t 0 From the lecture notes, Lecture 070 - Modulation and Demodulation using PLLs (09/01/03) Page 070-20. L() = AM and FM Modulation Can recover m(t) with envelope detector (see lecture 12 of 102a notes) M(Ss j Synchronous demodulation multiplies by the carrier and Chapter 7: Pulse Modulation Demodulation of PAM signals (continued) Single Sideband Modulation, SSB Demodulation SSB demodulation is a key to its successful use and application. Demodulation • DSB-SC modulation shifts spectrum to right and left by fc • To recover original signal m(t) from the modulated signal, it is necessary to Modulation Techniques the characteristics of the demodulator play a critical role in the overall performance Modulation and demodulation of FSK signals. A generic demodulator is shown in Figure 2. Notes on Quadrature Amplitude Modulation The probability density function for nI and nQ is a zero mean Gaussian 264. Modulation and Demodulation Chapter 9. of the other seven ideal phase references must be shifted by an amount equal to the recovered carrier phase. 264. Modulation and Demodulation Chapter 9. of the other seven ideal phase references must be shifted by an amount equal to the recovered carrier phase. Each pattern of bits forms the symbol that is represented by the particular phase.

Note that s(k) and m(n) are complex.$
