Digital fundamentals

1. diodes

   • When a junction is formed between N-type and P-type semiconductor materials, the resulting device is called a diode

2. transistors

   • Typical applications for transistors in aircraft electrical and electronic systems are controlling generator fi eld current, driving lights and warning displays, amplifying signals from sensors and transducers and for use as amplifying devices in cabin interphone and aircraft radio and navigation aids.

3. integrated circuits

   • Considerable cost savings can be made by manufacturing all of the components required for a particular circuit function on one small slice of semiconductor material (usually silicon).
