Amplifier Circuits: Audio & RF Preamplifier Circuits
Amplify signals before they go into circuits with these preamplifiers.
Sometimes signal levels are too low. Say for example that you want to listen to an FM or AM radio station that's really far away, but the signal is too low for you to listen top it comfortably over the static. A preamplifier circuit can amplify the signal before it reaches the receiver, which can help clear up the static because the signal is strong.
