WebOct 4, 2024 · Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth. WebThe factor is known as Q ( quality factor ). The higher the Q, the better the filter; the lower the losses, the closer the filter is to being perfect. Although Q may be defined in several ways, a general definition that applies to any system is based on the ratio of the energy stored in the system to the energy dissipated per cycle:

WebMay 22, 2024 · If the stop-band of band-stop filter is very narrow and highly attenuated over a few hertz, then that special type of band-stop filter is known as Notch filter.

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:

WebHere is a circuit diagram of notch filter. It is a circuit of active notch filter, as we can see operational amplifiers are used. We can also see, the circuit is combination of both low pass filter as well as high pass filter. The summing amplifier sumps up the output from the low pass filter and high pass filter.
