1. AUDIO AMPLIFIER TO FIND THE
RESONANT FREQUENCY
BY
TAYLOR SCHOTT

2. AUDIO AMPLIFIER
• Takes an input signal and uses an op-
amp to amplify the signal

3. WHY AN AUDIO AMP?
• Designed for use to broadcast signal at
higher frequencies.
• Typically used at concerts to project music
to large crowds.
• To achieve the resonant frequency of an
object.

4. • Requires specific tone that object projects
when it is hit with an outside force.
• Difficulties in keeping same tone and
finding the right matched frequency.
ACHIEVING RESONANT FREQUENCY

5. ACHIEVING RESONANT FREQUENCY
• Design of Circuit must have a very
low input voltage and high output
voltage to receive a large gain (Av).
