Minimizing quantization effects in a practical second-order digital filter bank
I. BOYD, Robert Linggard · International Journal of Electronics · 1984
The paper describes the solution to coefficient and product-quantization effects in a practical, real-time digital filter bank. The solution to the coefficient-quantization effects involves simple manipulation of the floating-point filter coefficients. A computer simulation of product-quantization errors enables the appropriate number of bits for the truncated products to be determined.
