Use MATLAB to plot the AM DSBSC modulated signals with modulation index m=0.25,0.5,0.8,1.0,1.2,1.5,2.0 with carrier signal c(t)=20cos(2pi20000t) and massage signal m(t)=Vm cos(2pi3000t) along with the envelope.
1. (9 points) In this Question, we are going to perform DSBSC modulation using MAT- LAB. The signal we want to use is a speech signal. Here is the block diagram of ths system we want to simulate: Modulation Demodulation ult gt) m(t) x Butterworth LPF mr(t) c(t) Gr(t) Figure 1: DSBSC modulation and demodulation. (a) Since we are working with speech signals, we will choose a sampling frequency that is much larger than the bandwidth of the signals. As...
Double Side Band with Suppressed Carrier (DSBSC) signal under Digital Sound Processing: Amplitude modulation (AM) technology is used where the modulating signal is given as ?(?)=1+5.5cos(9600??) while the carrier is given as ?(?)=2cos(96000??)+4cos (144000??). How do you obtain the receiver carrier and the bandwidth of the recovering filter so as to recover the modulating signal?
Select the correct statement regarding the difference between
the FM modulated signal waveform and the AM modulated signal
waveform.
a. The FM signal wave changes frequency according to the message
wave m(t). The "peak" amplitude of the FM signal, Ac=5, remains
constant.
b. There is no difference between the FM and AM signal waves
because they are both modulated by the same message wave, m(t) =
Amcos(2πfmt)
c. The AM signal wave frequency changes with the message wave m(t)
while...
Consider the following Amplitude Modulation (AM) signal given by Xc(t)=Ac[1 + μx(t)]cos(wct) where x(t) is the message signal, and μ the modulation index.
