Filters Tutorial 5: Passive First Order High Pass Filters



Published
Today we talk about Passive 1st order high pass filters, both RC and RL.
We will also introduce a formal technique to analyze such filters and, as a matter of fact, any circuit that presents one input and one output.

Although the math behind the concepts for this method seems daunting, we will see that we do not need to use it and, instead, we can use a simple graphic procedure to draw what are called Bode diagrams that describe how the circuits work.

We will also take some measurement in the lab to prove that the information, found from the graphics and the theory behind them, reflect exactly how the real life circuits work.

Happy Experiments!
