How to improve the output noise of a laboratory supply using LTspice

Video Description

#55 In this video I want to look at a problem I've had for quite some time now, and a problem you might also have. Its related to the laboratory power supply which in my case is a switch mode power supply and the output noise it generates. Its a very annoying problem and I set out to fix it by using the LTspice simulator to first understand what is going on and then checking the real circuit to make sure the simulation is accurate. Notice: Any modifications done to equipment should be done at your own risk. The equipment usually works with lethal voltages so extreme care is mandatory.
