Description
This app is used to calculate RL filter. It is suitable for hobbyist or electronic engineers.
Features:
1. Calculate cutoff frequency by resistor and inductor values
2. To find out combinations of resistance and inductance making a desired cutoff frequency
3. Save all combinations in a CSV (Excel) file
4. Use preferred values of resistors and inductors
Features in PRO version only:
1. Can use preferred value 1% for resistor and 5% for inductor
2. No Ads
3. No limitation
Note :
1. For those who need support please email to the designated email.
Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.
