Since we know that a recursive filter is stable if and only if all its poles have magnitude less than 1, an obvious method for checking stability is to find the roots of the denominator polynomial in the filter transfer function [Eq. ( 7.4 )]. If the moduli of all roots are less than 1, the filter is stable. See more Recall that theorder of a polynomialis defined as the highestpower of the polynomial variable. For example, the order of … See more Now consider what happens when we take the factored form of thegeneral transfer function, Eq.(8.2), and set to to get the frequency responsein … See more As defined earlier in §5.6 (page ), afilter is said to be stable if its impulse response decays to 0 as goes to infinity.In terms of poles and zeros, an … See more The phase response is almost as easy to evaluate graphically as is theamplitude response: If is real, then is either 0 or . Terms of theform can be interpreted as a vector drawn from the point to the point in the complex plane. … See more WebThe stability of a recursive filter depends on the phase spectrum of its denominator array. A two-dimensional generalization of the discrete Hilbert transform leads to a scheme producing stability with nominal distortions of the filter's desired amplitude spectrum. The method is therefore an attractive alternate to a least-squares procedure ...

WebRecursive digital ﬁlters are often known as I Inﬁnite Impulse Response (IIR) Filters as the impulse response of an IIR ﬁlter often has an inﬁnite number of coeﬃcients. IIR Filters I Require fewer calculations than FIR ﬁlters. I ∴ Faster response to the input signal, I and ∴ shorter frequency response transition width. However!
