This is a course project of DSP, Year 3, UESTC & Glasgow Joint School.
Simulate the DFT procedures:
- Set up sampling frequency
- Anti-aliasing filter
- ADC, sampling interval
- Windowing
- DFT
The input signal is $$ x(t)=10sin(2\pi64t)+sin(2\pi250t)+20sin(2\pi256t)+3sin(2\pi260t)+10sin(2\pi512t) $$ The sampling period is 1026Hz.
DFT-point is 513.
Types of windows: Rectangular, Hann, Bartlett, Hamming, Blackman.
