visualizeFilterStages

System object: dsp.DigitalDownConverter
Package: dsp

Display response of filter stages

Syntax

visualizeFilterStages(H)
visualizeFilterStages(H,'Arithmetic',ARITH)
hfvt = visualizeFilterStages(H)

Description

visualizeFilterStages(H) plots the magnitude response of the filter stages and of the cascade response. When you set the FilterSpecification property to Design parameters the method plots a mask based on the filter specifications. By default, the object plots the response of the filters up to the second CIC null frequency (or to the first when only one CIC null exists).

visualizeFilterStages(H,'Arithmetic',ARITH) specifies the arithmetic of the filter stages. You set input ARITH to double, single, or fixed-point. When object H is in an unlocked state you must specify the arithmetic. When object H is in a locked state the arithmetic input is ignored.

hfvt = visualizeFilterStages(H) returns the handle to the FVTool object.
