WELCOME TO DIGITAL SIGNAL PROCESSING DEMO
This demo shows 3 applications of signal
processing.
1) A signal is processed by a low pass filter
2) A signal is processed by a high pass filter
3) A signal is convolved with a specified function.

RADIO BUTTONS
1) Low pass filtering
The signal is processed by a low pass
filter that removes high frequencies.
Four plots show :
i) Original signal
ii) Power spectra
iii) Low pass Butterworth filter
iv) Filtered signal
2) High pass filtering
The signal is processed by a high pass
filter that removes low frequencies.
Four plots show :
i) Original signal
ii) Power spectra
iii) High pass filter
iv) Filtered signal
3) Convolution
The signal is convolved with another
signal as defined by the kernel.
Four plots show :
i) Original signal
ii) Filter (other signal)
iii) Convolved signal
iv) Signal minus the convolved signal
SLIDER
<<FILTER LENGTH>>
Select the filter length of the
convolution signal.
