Calculates the filter coefficients for a second order bandpass and performs filtering on input signal.
Second order transfer function used:
H(z) = (b0.z² + b1.z + b2) / (z² + a1.z + a2)
Inports
In: Input In(k)
Outports
Out: Output Out(k)
Mask Parameters
characteristic: The filter characteristic is one of Butterworth (=Bessel) or Chebyshev.
fc1: Lower cut-off frequency in Hz
fc2: Upper cut-off frequency in Hz
rc: Attenuation at cut-off frequencies.
ts_fact: Multiplication factor of base sampling time (in integer format).
