App description

Enter the cutoff frequency value, any resistor or capacitor value, any resistor Rc or resistor Rd, click Calculate. The result will be displayed.

Calculation formula:

R_a = resistance in the filter

R_b = resistance in the filter

(R_a = R_b)

C_a = filter capacitor

C_b = filter capacitor

(C_a = C_b)

R_c = feedback resistor

R_d = feedback resistor

Usage example

Input data: cutoff frequency: 100KHz

Click on "Calculate"

Output Data:

Resistance (R_a = R_b): 10Kohm

Capacitor (C_a = C_b): 0.159nF

Resistor R_c:10Kohm

Resistor R_d: 5.85Kohm

Note

Enter any value arbitrarily - resistor or capacitor

Any value - resistor R_c or resistor R_d
