Visualize response of filter cascade

Syntax

fvtool(H)
fvtool(H,..,'Arithmetic',ARITH,...)
fvtool(H,..., PROP1, VALUE1,PROP2,VALUE2)

Description

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

fvtool(H,..,'Arithmetic',ARITH,...) specifies the arithmetic of the filter cascade. 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.

fvtool(H,..., PROP1, VALUE1,PROP2,VALUE2) launches FVTool and sets the specified FVTool properties to the specified values.
