AM(Amplitude Modulation)调制是一种常见的模拟调制技术,通过改变载波信号的幅度来传输基带信号。在AM调制中,基带信号被乘以一个高频载波信号,产生一个带有两个边带的调制信号。这两个边带位于载波频率的上下方。 FM(Frequency Modulation)调制是一种模拟调制技术,通过改变载波信号的频率来传输基带信号。在FM调制中,基带...
Frequency modulation collapse all in pageSyntax y = fmmod(x,Fc,Fs,freqdev) y = fmmod(x,Fc,Fs,freqdev,ini_phase)Description y = fmmod(x,Fc,Fs,freqdev) returns a frequency modulated (FM) signal y, given the input message signal x, where the carrier signal has frequency Fc and sampl...

Ais the carrier amplitude. fcis the carrier frequency. x(τ) is the baseband input signal. fΔis the frequency deviation in Hz. The frequency deviation is the maximum shift fromfcin one direction, assuming|x(τ)| ≤ 1. A baseband FM signal can be derived from the passband representation ...
