What is a feedback system?
Think about how systems regulate themselves.
Name the two types of feedback.
Remember how they affect output.
What type of feedback reduces the output gain inconsistencies?
Think about which feedback stabilizes the system.
True or False: Positive feedback stabilizes the output.
Consider the effects each type of feedback has.
A feedback amplifier has a gain (A) of 10 and a feedback factor (beta) of 0.2. Calculate the desensitivity factor.
Use the formula for desensitivity factor.
Explain how variations in loop gain affect the performance of a control system.
Consider both sides of the feedback process.
