Learn to read and create radio circuits.
In the first episode, you will learn how to navigate radio circuits. You will be able to distinguish between the main types of amplifying devices. Common-emitter, common-base, common-collector circuits and similar on tubes and field-effect transistors. Various filters, blocking capacitors, power supplies and others. Let's design a real microphone amplifier and a tube amplifier. Explanations of the purpose of all elements in the diagrams.
