This section of MATLAB source code covers AM,FM,PM modulation in matlab. It mentions the same using modulate matlab function. Modulate matlab function%Parameters for signal creation Fs = 8000; %sampling frequenc
This MATLAB function returns a frequency modulated (FM) signal y, given the input message signal x, where the carrier signal has frequency Fc and sampling rate Fs.
Use the FM modulators to apply FM modulation to the signalx. y1 = fmmod1(x); y2 = fmmod2(x); Plot the spectra of the two modulated signals. The larger frequency deviation associated with channel 2 results in a noise level that is 10 dB higher than the first channel. ...
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...
