Description
"High pass IIR filter" applies an IIR highpass filter to the given signal x.
Its parameters are

- "Butterworth" (0)
- "Chebyshev" (1)
- "Elliptic" (2)
- Filter order n
- Pass band ripple in dB (Chebyshev and Elliptic only)
- Attenuation atten in negative dB (Elliptic only)
- Pass band edge frequency f0 in reciprocal units of the x-axis
