#133 In this video I start looking and some of the special characteristics that filters need to have when talking about common mode and differential mode noise. Based on the type of noise you want to filter you will need to take into consideration specific characteristics and you will also need to be aware of the noise circuit and the impedances present.

#117 In this video I start testing the LISN to see just how good it is. I look at multiple things starting with output impedance then go for insertion loss, input impedance and input side filtration and finally look at inter-channel isolation or cross talk.
