The following table specifies the input parameters of the General Purpose Filters
function.
Parameter Description
GP filter 1 sel Selects input to general purpose filter 1
GP filter 2 sel Selects input to general purpose filter 2
GP filter 3 sel Selects input to general purpose filter 3
GP filter 4 sel Selects input to general purpose filter 4
Function outputs
The following table specifies the output variables of the General Purpose Filters
function.
Variable Description
GP filter 1 output General purpose filter 1 output
GP filter 2 output General purpose filter 2 output
GP filter 3 output General purpose filter 3 output
GP filter 4 output General purpose filter 4 output
Function configuration
The following table specifies the configuration parameters of the General Purpose
Filters function.
Parameter Description
GP filter 1 bndwth General purpose filter 1 bandwidth
GP filter 2 bndwth General purpose filter 2 bandwidth
GP filter 3 bndwth General purpose filter 3 bandwidth
GP filter 4 bndwth General purpose filter 4 bandwidth
Function description
The operation of general purpose filter 1 is described here. Each of the four general
purpose filters behaves in the same manner.
The input, output, and bandwidth of general purpose filter 1 are defined as follows:
Input = Variable selected by GP filter 1 sel
Output = GP filter 1 output
Bandwidth = GP filter 1 bndwth
