WebApr 5, 2015 · First, you need to measure the actual response of your filters. I'd expect that the notch frequency is inversely proportional to the value of the two .220 uF capacitors. If … WebNotch filters are rated based on their Q-factor. Generally, the higher the Q-factor, the more exact the notch. A notch filter with a low Q-factor may effectively notch out a range of frequencies, whereas a high Q notch filter will only delete the frequency of interest.

http://learningaboutelectronics.com/Articles/Quality-factor-calculator.php WebAs the gain is reduced, the -3dB passband BW is also reduced giving an apparent increase in Q or filter shape factor. 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. Also note that: WebUsing cascading, design an active low pass filter with the following specifications:Amax = 1 dBAmin = 30 dBfp = 20 kHzfs = 40 kHzThe filter order N should be as small as possible.

WebHigh Q filters allow very sharp filter roll-offs. In terms of the s-plane, high Q filters have their poles located closer to the jw axis. ... the filter resulting in a higher performance amplifier than expected to ensure it does not limit adversely affect the filter response. To obtain a slightly higher Q, lets move to the multiple feedback ... 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.
