**drawing a high-pass filter (HPF), type RC, in LaTeX using TikZ and CircuiTikZ** packages. It's an** **electronic filter that **passes signals** with a **frequency higher** than a certain **cutoff frequency** and **attenuates signals** with **frequencies lower** than the **cutoff frequency**.

RC high pass filter drawn in LaTeX using CircuiTikZ

## Short description

- The RC high pass filter circuit diagram has two electrical components: a resistor and a capacitor. Both components have labels (R for the resistor and C for the capacitor). In addition, it has voltage labels which can be created by using the open circuit element. Moreover, the circuit is drawn above a rectangle filled with cyan color. Check the code below!
