Visualize response of filter cascade


fvtool(upConv,..., PROP1, VALUE1,PROP2,VALUE2)


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

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