      MaskHelp		      "This block implements a combination of switches and an FIR filter. By using appropriate combinations of DIP switches 0 and 1, it is possible to get filtered and unfiltered signals from Line-in or stored variable to the DSP board output.  Put the FIR filter coefficients in the variable dialog box. By default, it takes the values from the variable Num in the Matlab workspace."
