getNumStages

Get number of stages in filter cascade

Syntax

getNumStages(FC)

getNumStages(FC) returns the number of stages in the dsp.FilterCascade object, FC.

This example shows how to query the number of stages in a filter cascade.

Create a filter cascade with two stages and call getNumStages on the cascade object.

    FC = cascade(dsp.FIRFilter,dsp.IIRFilter)

FC = 
  dsp.FilterCascade with properties:

         Stage1: [1×1 dsp.FIRFilter]
         Stage2: [1×1 dsp.IIRFilter]
    CloneStages: true

    FCstages = getNumStages(FC)

FCstages = 
2

Filter cascade, specified as a dsp.FilterCascade System object.
