About

This YouTube channel is intended for the "Inquisitive Experimenter" who is interested in Electronics. What do I mean by that? This is the person who want to dig a little deeper, who wants to understand what goes on behind the scenes, they 'WHY' behind things, but, at the same time, doesn't want to have to have a masters degree in engineering to understand. I try to answer questions and provide the hard to find information. I divide my videos up into two groups: The numbered videos (e.g. 001, 002 ...) are the more basic videos covering foundational stuff, but still at a somewhat deeper level than the average, mainstream contents you find on the Internet. When there is a series, a letter is appended to the number to keep them in order. The lettered videos (e.g. 00a, 00b, 00c) are the more 'advanced' videos with more technical content. In these I assume basic knowledge of stuff. If there is a series, I append a number after the letter to keep them in order.

Video Description

This video is all about introducing you to the world of Impedance Matching. For most folks who think about this, it can be quite an intimidating subject. "I could never do that!" is the common mantra. It turns out, however, that is isn't as hard as it seems on the surface. I want to emphasize ... YOU CAN DO THIS! I want to help you to gain some confidence and the skill to do this. In this video I will introduce you to the goal of Impedance Matching as well as the two methods you could use to do it. One of these two methods is the oft avoided Smith Chart (of itself is more intimidating than it needs to be). I will help you tiptoe into the shallows of the aspects of the Smith Chart you need so you can perform Impedance Matching using discrete components like capacitors and inductors. In the next video I am going to be using the Smith Chart to actually design an Impedance Matching circuit using the principles learned in this video. If you can read a road map and find your way from point A to point B, then YOU CAN DO THIS!
