  • 8Transistor AmplifiersMany of the AC signals you’ll work with in electron-ics are small. For example, the signal that an opti-cal detector reads from a DVD disk cannot drive a speaker, and the signal from a microphone’s output is too weak to send out as a radio signal. In cases such as these, you must use an amplifier to boost the signal.The best way to demonstrate the basics of amplifying a weak signal to a usable level is by starting with a one-transistor amplifier.
