 """ Generates the b and a coefficients for a butterworth bandpass IIR filter. Parameters CenterFreq : float central frequency of bandpass bandwidth : float width of the bandpass from centre to edge SampleFreq : float Sample frequency of filter order : int, optional order of IIR filter. Is 5 by default btype : string, optional type of filter to make e.g. (band, low, high) Returns ------- b : ndarray coefficients multiplying the current and past inputs (feedforward coefficients) a : ndarray coefficients multiplying the past outputs (feedback coefficients) """
