5.5.10 FIRStructInit

Description

FIRStructInit initializes the values of the parameters in an FIRStruct FIR Filter structure.

Prototype

void FIRStructInit (FIRStruct* filter, int numCoeffs, fractional* coeffsBase fractional* delayBase);

Arguments


Parameters	Description
filter	Pointer to the FIRStruct filter structure
numCoeffs	Number of the filter coefficients (also M)
coeffsBase	Base address for the filter coefficients (also h)
delayBase	Base address for delay buffer

Returns

None.

Remarks

See description of FIRStruct structure above.

Upon completion, FIRStructInit initializes the coeffsEnd and delayEnd pointers, accordingly. Also, the delay is set equal to delayBase.
