This is the final project of ICE2605, Signals and System, IEEE Honor Class, SJTU. My lecturer is Bo Jiang.
Contents:
- Report and figures are stored in the folder named "report and figure".
- Codes are stored in the folder named "code and audio".
- The folder named "part1" stores the MATLAB code for part1.
- part1.m is the main program, you can just run it in your MATLAB terminal with command
part1. - PlotWave.m is used to plot the waveform of a signal.
- PlotSpectrum.m is used to plot the complete spectrum of a signal.
- PlotSpectrumLocal.m is used to plot the spectrum of a signal in the interval of
$[-f,f]$ . - ILPF.m is an ideal lowpass filter, which can eliminate the high frequency components (larger than a specific cut-off frequency) completely.
- spring.wav is an audio clip from the soft music named Spring written by Joe Hisaishi.
- part1.m is the main program, you can just run it in your MATLAB terminal with command
- The folder named "part2" stores the MATLAB code for part2.
- part2.m is the main program, you can run it in your MATLAB terminal with command
part2. - Plotwave.m, PlotSpectrum.m and PlotSpectrumLocal.m are the same as those in part1.
- ta.wav is the original audio clip, and ta0.wav-wa6.wav are the sampled version of ta.wav
- part2.m is the main program, you can run it in your MATLAB terminal with command
- The folder named "part1" stores the MATLAB code for part1.
