Returns the error string associated with the digital filters. The return string has three fields separated by commas: "stage1 status, stage2 status, stage3 status"

Each of these fields can contain one or more of the following error codes:

• NO ERROR  

• *NUMBER-OF-COEFFICIENTS -  the number of coefficients is excessive for that filter-stage

• *COEFFICIENT VALUE - one or more coefficients are out of range for that filter-stage

• *SUM-OF-COEFFICIENTS - the sum of all coefficients is excessive for that filter-stage,

• *FREQUENCY - the frequency for Stage 1 is out of range (only applies stage1 field),

• *PARAMETER - one or more parameters are out of range (only applies to stage 3 field)
