An analytical procedure for critical frequency tuning of FIR filters
Pavel Zahradník, Miroslav Vlček · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 2006
A novel analytical procedure for the tuning of finite-impulse response (FIR) filters is introduced. The tuning procedure adjusts a single frequency of the frequency response to the desired value while preserving the nature of the filter. The impulse responses of the original and of the final filter are related by the transformation matrix. Two examples in the analytical design of notch FIR filters demonstrate the usefulness of the proposed tuning procedure.
