Description

This app is used to calculate the RC charging circuit and RC filter. It is suitable for hobbyist or electronic engineers.

Features:
1. Calculate time constant by R and C
2. Calculate between time constant and % of charging
3. Calculate cutoff frequency of low-pass filter/ high-pass filter by resistor and capacitor values
4. To find out combinations of resistance and capacitance making a desired time constant
5. To find out combinations of resistance and capacitance making a desired cutoff frequency
6. Save all combinations in a CSV (Excel) file

Features in PRO version only:
1. No Ads
2. 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.
