Low Pass & High Pass Filter Calculator
This calculator allows you to determine the cutoff frequency (Fc) of a low pass or high pass RC filter. These filters are essential in electronics for shaping signal bandwidth and reducing noise.
Formula: Fc = 1 / (2Ï€RC)
What is a Low Pass and High Pass Filter?
Low Pass Filters allow frequencies below the cutoff frequency to pass and attenuate frequencies above it.
High Pass Filters do the opposite – they allow higher frequencies to pass and block lower ones.
Where Are These Filters Used?
- Audio signal processing
- Microcontroller input smoothing
- Analog sensor filtering
- RF circuits and transmission lines
