Compare classical Butterworth, Chebyshev, and elliptic designs. Explore Bessel, Yule-Walker, and generalized Butterworth filters.
Use windowing, least squares, or the Parks-McClellan algorithm to design lowpass, highpass, multiband, or arbitrary-response filters, differentiators, or Hilbert transformers.
Filter signals using the
Eliminate the phase distortion introduced by an IIR filter.
Use indexing to counteract the time shifts introduced by filtering.
Remove delays and distortion introduced by filtering, when it is critical to keep phase information intact.
Use a differentiator filter to differentiate a signal without amplifying the noise.
filterBuilder is a graphical interface that speeds up the
filter design process.
Generate realistic guitar chords using the Karplus-Strong algorithm and discrete-time filters.
