TFilterType Type

Summary

Defines FIR filter types.

Declaration

TFilterType = (ftLowPass, ftHighPass, ftBandPass, ftBandStop,
                     ftHilbertIII,ftHilbertIV,
                     ftDifferentiatorIII,ftDifferentiatorIV,
                     ftDoubleDifferentiatorIII,ftDoubleDifferentiatorIV,
                     ftIntegratorIII,ftIntegratorIV,
                     ftDoubleIntegratorIII,ftDoubleIntegratorIV);

Value	Description
ftLowpass:	design a lowpass filter.
ftHighPass:	design a highpass filter.
ftBandpass:	design bandpass filter.
ftBandStop:	design a bandstop filter.
ftHilbertIII:	design a type III hilbert transformer.
ftHilbertIV:	design a type IV hilbert transformer.
ftDifferentiatorIII:	design a type III differentiator.
ftDifferentiatorIV:	design a type IV differentiator.
ftDoubleDifferentiatorIII:	design a type III differentiator.
ftDoubleDifferentiatorIV:	design a type IV differentiator.
ftIntegratorIII:	design a type III integrator.
ftIntegratorIV:	design a type IV integrator.
ftDoubleIntegratorIII:	design a type III integrator.
ftDoubleIntegratorIV:	design a type IV integrator. Not all routines accepting TFilterType variable can design all filter types. All IIR filter design routines are limited to ftLowpass, ftBandpass, ftHighpass and ftBandstop filter types.

Description

Define the FIR filter type to be designed:
