Q = f c / Δ f ( − 3 d B) To optimize this filter, you must choose realistic pass BWp (-3dB) and stop BWs (-30dB) for a given center frequency. Expecting more requires more stages or tweaking of R.

Webusing analog circuitry (such as a twin-T notch filter) [11][12] or, as is more common now, by using digital processing techniques (e.g. a finite impulse response notch filter) [13]. The challenge, in both cases, is in aligning the high-Q notch to be and stay exactly at the line frequency and is solved by using tracking techniques.

WebOct 12, 2013 · $\begingroup$ Assuming this is for a fixed frequency you will need a filter design program to generate the coefficients. It's going to be tedious though - if you really do need high Q and linear phase then the filter may well have hundreds of coefficients and the design process could be slow and painful. http://www.seas.ucla.edu/brweb/papers/Journals/BR_SSCM_SPR_18.pdf
