The formula for calculating cutoff frequency for an RL filter circuit is: fc=R2πLfc=2πLRFigure 3: Circuit diagram of a high pass RL filter. The corner frequency formula for high-pass filter circuits and low-pass filter circuits is the same. How to calculate cutoff frequency? Let us calc...
Enter the Cutoff Frequency Desired: This RL cutoff frequency calculator calculates the cutoff frequency point of the low pass filter, based on the values of the resistor, R, and inductor, L, of the circuit, according to the formula fc= R/(2πL). To use this calculator, all a user ...
My first post. I came up with the exact same equation asomar-rodriguezfor the -3 dB cutoff frequency for an LC circuit. And like Omar, I am amazed that so many people are assuming the equation 1/(2π sqrt(LC)) is the -3 dB cutoff frequency. That's wrong! That equation is for ...
