Good morning to all and I hope you are doing well.
I notice that all kinds and types hang out here. Generally they are loosely categorized as those who need help and those that can give help. Me I am trying to learn and in so doing... I try to share. I'd like to post links to two videos I found (there may be more there that are useful) that explain and even demonstrate a couple of concepts found in communications radios. I hope nobody minds.
First up, "diodes as a switch". I knew that they were in there.... I just never gave any thought to how they are doing what they do. This is a pretty neat video where it is described what is going on...and then a couple of bench experiments with lab equipment that demonstrate how it works>
Next, the concept of RF Mixing and IFs. Again, I have had the theory in my head but this explanation and demo really helps get a picture of what is going on.
I can only hope that some might find it useful....
