I have an assignment about Signals and Systems. Details are given below.
Generate a noisy signal with sinusoidal components defined at 100 Hz and 300 Hz (3rd Harmonic)
a) Calculate (slow) its time and spectral variation
b) Calculate frequency resolution (deltaf)
c) Design a low pass filter to remove the 3rd harmonic and check its performance.
Fourier Transform will be used in the assignment.
I need the code and the graphs to do this assignment. Codes will be taken as .txt format. Thank you.
