Q and bandwidth
http://web.mit.edu/6.101/www/labs/FT08LAB1.pdf WebThe “Q” of a band pass filter is the ratio of the Resonant Frequency, ( ƒr ) to the Bandwidth, ( BW ) between the upper and lower -3dB frequencies and is given as: So for our simple example above, if the bandwidth (BW) is 400Hz, that is ƒH – ƒL, and the center resonant frequency, ƒr is 346Hz.

Web2 days ago · Therefore, the bandwidth should be: \[BW=\frac{f_0}{Q_L}=\frac{1 \text{ } GHZ}{1}=1 \text{ }GHz\] This equation is in reasonable agreement with the simulation result. On the other hand, for the T-network, the upper and lower 3 dB points are at 1.29 GHz and 750 MHz, leading to a bandwidth of 540 MHz. As we can see, a T-network allows us to ... http://www.sengpielaudio.com/calculator-bandwidth.htm
WebVisually, a high Q factor means a narrower, steeper, and sharper EQ. A low Q factor means a wider, more shallow, soft EQ. It’s definitely more important to understand bandwidth and Q in practice than in technical terms. Still, the two words get conflated often. To be clear, bandwidth and Q are not one in the same!

WebJan 20, 2024 · The bandwidth can then be given in terms of resonant frequency and quality factor using the following formula: BW = fr / Q . However, the formulas for calculation of impedance (Z) and quality factor (Q)of parallel AC circuit is different from that used to calculate those values in a series circuit. In Parallel Z = L/RC and Q = R/XL
