# RC Network

An

**RC network** is an

electrical network that is constructed using a

resistor and

capacitor in

parallel, and acts as an effective

high-pass filter. Its cutoff

frequency is calculated using the following equation:

Where:

- &pi is about 3.1415926
- C is the capacitor value
- R is the source impedance
