When the signal 𝑚(t) = 2sin(2π100t) +5cos(2π110t) is given to
the system above
A double sideband modulated signal is obtained at the system
output. carrier signal
frequency is 500 Hz.You can take sampling frequency 10 times the
carrier frequency.
According to this;
All of these steps must be done with matlab
codes.
a) The amplitude spectrums of the signals at (a) and (b) in the
figure are the same
on the window, draw one under the other in the range of
[-fs/2,fs/2] Hz.
b) For the signal (c) at the system output to be a double sideband
modulated signal
What type of filter is needed, determine? Amplitude response of the
filter |H(f)| and phase
answer ∡𝐻(f) on the same shape window in the range of [-fs/2,fs/2]
Hz
draw it below.
c) The amplitude spectrum of the signal (c) at the system output in
the range of [-fs/2,fs/2] Hz.
draw it below.
Note: After filter design to filter the
sign
use the function of y=filter(b,a,x) .
Note: Make the necessary information using
the comment lines.
