Feedback: More than Loud Noise and Joysticks James Wnorowski
What is Feedback? • When you put a microphone too close to a speaker? • Force Feedback Joysticks? • Something else entirely?
Stability • Which pendulum is stable, and why? • Both placements are in equilibrium. • What happens if I push each mass a little to the side?
Demo • The first time, I just let the flashlight fall • The second time, I moved my hand so that it was under the flashlight, preventing it from falling • This is an example of Negative Feedback
Review • To make systems stable, we use Negative Feedback. • Joystick an example of Negative Feedback. • Speaker / Microphone combination an example of Positive Feedback.
