Syntax

showSpecificationMask(fa,showit)
showSpecificationMask(___,DisplayNums=dispnums)

Description

showSpecificationMask(fa,showit) shows or hides the filter specification mask on the active display in the Filter Analyzer app fa, depending on whether showit is true or false, respectively. For the app to show a mask:

  • There must be only one filter plotted in the display.

  • The filter must contain design metadata. To include metadata in your design, use a digitalFilter object or a filter System object™.

  • You must specify the Analysis argument of fa as either "magnitude" or "magestimate". You must not specify an overlaid analysis.

example

showSpecificationMask(___,DisplayNums=dispnums) shows or hides the specification mask on the displays specified in dispnums, in addition to the input arguments from the previous syntax.
