#260 In this video I look at how diodes can be used to switch signals - while any diode can work as a switch, there are multiple ways in which the diodes proprieties can be leveraged for this goal. I look at how a normal PN diode behaves but also a dedicated PIN diode in a switch application.

![EMC tutorials - [3/3] Improving the LISN... sort of...
#127 In this video I try to improve on the original design of the LISN by addressing some of its issues and taking a more detailed look at the inter-channel isolation. Things dont turn out exactly as planned but some valuable insight can be observed nonetheless.

![EMC tutorials - [1/3] Building an LISN
#114 In this video I look at the specifications and parameters behind a line impedance stabilization network, or LISN. I look at what is the purpose of the various components is and then take a closer look at how the values need to be chosen. Finally I build such a device.
