A multi-output wave - digital biquad using magnitude truncation instead of controlled rounding
Hon Keung Kwan · IEEE Transactions on Circuits and Systems · 1985
The use of magnitude truncation instead of controlled rounding for the elimination of zero-input and constant-input oscillations in the wave digital biquad derived from the feedforwardRC-active configuration is described. We also describe how the structure could be used for the simultaneous realization of all types of second-order digital filters.
