releaseStages

Release locked state of all stages in cascade

Syntax

releaseStages(FC)

Description

releaseStages(FC) calls the release function of each individual stage in the dsp.FilterCascade System object™ FC.

For instance, if a dsp.FilterCascade object consists of a dsp.FIRFilter and a dsp.FIRInterpolator object, the releaseStages function calls the:

• release function of the dsp.FIRFilter object

• release function of the dsp.FIRInterpolator object

Examples

Release Stages of a Filter Cascade

Note: This example runs only in R2016b or later. If you are using an earlier release, replace each call to the function with the equivalent step syntax. For example, myObject(x) becomes step(myObject,x).

Create and release stages of a filter cascade.

firfilt = dsp.FIRFilter;
y = firfilt(randn);
FC = dsp.FilterCascade(dsp.FIRInterpolator, firfilt);
isLocked(FC.Stage2) 

ans = logical
   1

releaseStages(FC);
isLocked(FC.Stage2) 

ans = logical
   0

Input Arguments

FC — Filter cascade

dsp.FilterCascade System object

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