Next let us describe characteristics of the required shaping filter. After the required input signal has been either recorded or obtained, the characteristics of the shaping filter must be specified. The filter design can be used to determine a variety of shaping filters for the given input signal. Design options can include computation of inverse, band-pass, dephasing, minimum-phase, or spiking filters. An ideal inverse filter is the full amplitude and phase inverse of the given input signal. A band-pass filter can convert the input signal into a zero-phase band-pass signal or a minimum-phase band-pass signal.
