This passive RL low pass filter 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 must do is enter any 2 values, and the calculator will compute the 3rd field.

Typically they should be 1% or better. A further item to ensure the optimum operation of the circuit is to ensure that the source impedance is less than about 100 ohms. Additionally the load impedance should be greater than about 2 M Ohms. More info about Active Band Pass Filters can be found here or here or with the help of Google.

RC Low Pass Filter - Frequency and Bode Plot Calculator This tool calculates the crossover frequency for a RC low pass filter. In addition, it graphs the bode plot for magnitude in decibels and the phase in radians. The graph is unable to plot below 1Hz at the moment. The output frequency is rounded to the second decimal place.
