“Google search”????
I have 25+ years at the RF job. I, for one, don’t need a google search to tell me about RF engineering and digital communications. You do.
“Digital” communications ride on an RF carrier wave that is analogue, even when frequency hopping. In fact, there is no such thing as a digital electronic part. Digital is a form of description of an analogue technique. All digital components are made from analogue parts.
I call BS that you are an engineer.
