- It is used by ham radio enthusiasts with Arduino controllors.
- First steps in Software Defined Radio (SDR)
- Mixer theory

Transformer Design
Capacitors
- Murata's comparison of monolithic ceramic capacitors as compared to Tantalum capacitors. Note that monolithic ceramic capacitors values decrease if you put larger DC voltages across them though. The effective series resistance and temperature behavior are much better though.
- The markings on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.
