High Pass Filter Calculator - Learning about Electronics

WebThe resistor R2 and resistor R1 determine the gain of the circuit. The gain of the circuit is determined by the formula, gain (AV)= 1+ R2/R1. For this calculator, a user just has to enter the cutoff frequency and the gain desired. The calculator will then compute the resistor R, capacitor C, resistor R2, and resistor R1. WebIn an ideal design, a digital filter has a target gain in the passband and a zero gain (−∞ dB) in the stopband. In a real implementation, a finite transition region between the passband and the stopband, which is known as the transition band, always exists. The gain of the filter in the transition band is unspecified. trisha dixon tourshttp://www.earmark.net/gesr/opamp/bpf_adj.htm trisha doucette

"WebThe formula is shown by, f center = √ f1 f2 However, for narrowband bandpass filters where the ratio of f 2 /f 1 is less than 1.1, the center frequency can be approximated by the addition of the 2 cutoff frequencies divided by 2. This is shown in the formula, f center = (f 1 + f 2 )/2. " - Passband gain calculator
