A narrower bandwidth results in a high Q factor with a steep, sharp slope. Peak and notch filters These two filter types extend from bandpass filters, but take it to the extreme. This is where the high Q factors come into play. Rather than just aim for a range of frequencies, peak and notch filters target one specific frequency.

Four separate high-Q band-pass filters are then used to isolate each of the desired frequencies, and the component values for these filters are listed in Table 1. (Values for use with 50 Hz. power systems are shown in Table 2.) A variable phase shift circuit is also provided to ensure maximum rejection capability of the hum.

High quality filters are a critical component in the test and measurement of high-precision data acquisition (DAQ) systems. However, realizing a high-quality filter at low frequencies with passive components requires large inductors that are both size and cost prohibitive.

A narrow bandwidth (high Q) is particularly useful for removing unpleasant tones. Let’s say the snare drum in your mix has an annoying ring. With a very narrow bandwidth, you can isolate the offending frequency (usually around 1 kHz) and remove, or reject, it. This type of narrow band-reject filter is also known as a notch filter.

Impact of Q in Audio Filter Design • High Q designs tend to have sharp roll off – Sharp frequency roll off is a good thing • Disadvantages of high Q – Component values become very critical – High Q causes large delay variations across the bandwidth • Filters with low delay variation tend to “sound” better (key point )
Q factor vs bandwidth in octaves band filter -3 dB pass ...

A high filter quality means narrow-band filtering (notch), with a large Q factor. This results in steep filter flanks with a small bandwidth. A low filter quality means broad-band filtering, with a small Q factor. This results in flat filter flanks with a large bandwidth. The larger the Q the more narrow is the resonance peak. The smaller the Q the more broad is the resonance peak.

At a Q of 10, there exists just a 10-dB notch, and a 30-dB notch at a Q of 1. It seems that notch filters are unable to accomplish as high a frequency as we would likely anticipate, nevertheless the THS4032 is simply a 100-MHz device. It is natural to anticipate superior functionality from components with an improved unity-gain bandwidth.

The lowest Q setting sort of splits the difference between the V-EQ4’s low and high Q settings but tends toward the lower Q. This was likely designed for general tone shaping. The medium setting is a bit more drastic — but not quite as much as the MEQ-5. ... The audio steps through each of the filter modes in the same order as the images ...
