Abstract
A periodically time-varying linear second-order digital filter is analysed. It is shown that the technique of periodically varying the coefficients leads to significant savings in coefficient word length in the design of notch and narrow-bandpass digital filters having high-Q pole pairs. © 1986, The Institution of Electrical Engineers.
