A tighter practical bound on quantization errors in second-order digital filters with complex conjugate poles
Z. Ünver, K. Abdullah · IEEE Transactions on Circuits and Systems · 1975
An infinite series expansion of a sinusoid is used to find a tighter practical bound on quantization errors for second-order digital filters with complex conjugate poles. It is shown that the use of this new practical bound yields closer values to the lowest bound known which is impractical to calculate.
