If this coefficient - is multiplied by a data sample with value -1.0, the - result is -1.0 instead of +1.0 as expected. This is - because +1.0 cannot be represented in a signed, 2's - complement, fractional system. - - (2) The filter coefficients must be carefully selected - to prevent overflow. If there is a possibility of - overflow with a set of filter coefficients, then all - coefficients must be scaled by a constant value. The - DSP56200's 24-bit coefficients allow plenty of room - for scaling.

If this coefficient + is multiplied by a data sample with value -1.0, the + result is -1.0 instead of +1.0 as expected. This is + because +1.0 cannot be represented in a signed, 2's + complement, fractional system. + + (2) The filter coefficients must be carefully selected + to prevent overflow. If there is a possibility of + overflow with a set of filter coefficients, then all + coefficients must be scaled by a constant value. The + DSP56200's 24-bit coefficients allow plenty of room + for scaling.
