ABSTRACT:
Gain correction for a digital filter is accomplished by multiplying each data value by a coefficient representing the impulse response of the filter to form a convolution of the data values; accumulating the sum of the product of each multiplication to obtain a complete convolution; determining the difference between the positive full scale output and the negative full scale output of the filter; combining this difference with the ideal full scale output value to obtain the gain error factor; dividing the gain error factor by the full scale ideal value to obtain the gain correction factor; multiplying the negated accumulated sum of the product of each multiplication by the gain correction factor to obtain the gain error adjustment factor and combining the gain error adjustment factor with the accumulated sum to compensate for gain errors in the filter output.
