In case d the signal frequency is 4.125 kHz The sampling frequency of 8 kHz is not twice the signal frequency. Therefore aliasing will occur.
In case e the signal frequency is 4.0625 kHz The sampling frequency of 8 kHz is not twice the signal frequency. Therefore aliasing will occur.
Use the MATLAB script file in problem 6.2 to get the plots.
