# Tuned Amplifier

The tuned amplifier is used to amplify a specific frequency or a narrow band of frequencies, for which it is tuned. Tuned amplifiers are most commonly used for amplification of high frequency or radio frequency signals (30kHz to 300MHz), because radio frequencies are generally single and tuned circuits allow the desired radio frequency signal while rejecting all other frequency signals. There are two types tuned amplifiers such as

1. Single tuned voltage amplifier
2. Double tuned voltage amplifier

# Single Tuned Voltage Amplifier

Single tuned voltage amplifier with capacitive coupled

# Double Tuned Voltage Amplifier

The double tuned voltage amplifier
