Feedback Control – Why Should You Care?

• Microphone a Amplifier a Speaker a Microphone

• This loop happens so fast that it generates its own frequency

• Microphone-to-speaker distance dictates the frequency

– Decides how quickly sound “feedback” occurs through the system

• This feedback problem happens in public address systems

Feedback Control – Why Should You Care?

Attach a set of speakers to your computer

“Un-mute” and set microphone and speakers to maximum volume

Tap microphone and hear it in the speakers

Place speakers near microphone, turn up the volume and hear feedback

Change distance between microphone and speakers to see the effect

Caution: Not to be used as revenge on instructors, labmates, etc.
