    getLPSynWaveForm Method (AnWTFilter)
    In This Topic
    Returns the equivalent low-pass synthesis waveform of a cascade of filters, given the syhthesis waveform of the previous stage. This is the result of upsampling 'in' by 2, and concolving it with the low-pass synthesis waveform of the filter. The length of the returned signal is 2*in_l+lp_l-2, where in_l is the length of 'in' and 'lp_l' is the lengthg of the low-pass synthesis filter.

    The length of the low-pass synthesis filter is getSynLowNegSupport()+getSynLowPosSupport().
