WebNov 15, 2014 · 4. For the analog S-plane, the Q factor depends on the angle of the complex pole p from the horizontal axis, θ = arg p: damping factor ζ = 1 2 Q, and ζ = cos ( θ), and θ = arg ( p) so Q = 1 2 cos ( θ) = 1 2 cos ( arg ( p)) Right? But in the Z plane, the curves of constant Q are more complicated: So how do you get the Q of a complex pole?

WebFinally, q means the Quality Factor of the notch-filter. How to use a notch filter ? When there is a need to reject a certain narrow band of frequency, a notch-filter is used. A notch-filter is placed after any source from which the signal needs to be eliminated. In most cases, the filter is set as the very last component of any circuit. WebAbstract. Polyadenylation [poly(A)] signals (PAS) are a defining feature of eukaryotic protein-coding genes.
