Here are three articles from Electronic Design that you might find amusing. Electronic Design is a magazine for electronics engineers, but these articles have good information for amateur radio operators as well…..Dan
A Closer Look at the Common Emitter Amplifier and Emitter Follower.
Usually targeted at audio applications, these circuit blocks find homes in all types of designs. Here’s a quick study of their operation and properties.
I’m not sure why the author decided to use a 2N5550 instead of the more common 2N2222 for this article, but it’s a good explanation of how the common emitter amplifier works. If you’ve never breadboarded one, I’d suggest that you do so and play around with it.
Capacitor Basics and Their Uses in Power Applications.
Capacitors play key roles in the design of filters, amplifiers, power supplies and many additional circuits. Here’s a brief guide to the different types and the applications they’re best suited for.
How to Evaluate Oscilloscope Signal Integrity.
Oscilloscope signal integrity impacts signal shape and measurement values. This article is intended to help you assess the signal integrity of your oscilloscope and make trustworthy measurements.
