2 cards from this section. Quick, good the night before a test.
What is the main purpose of sampling in a feedback system?
Think about the role of feedback in control systems.
Explain the difference between shunt sampling and series mixing.
How do these configurations affect the flow of signals?
What configuration indicates voltage sampling?
Remember how we achieved voltage feedback!
The term 'Loop Gain' describes what?
What happens to output when feedback is strong?
An amplifier with a transconductance of 3 S has an input voltage of 2 V. Calculate the output current.
Use the transconductance formula and rearrange it.
If the feedback factor β is 0.1 and the loop gain is -β*A = -0.5, what is A?
Reorganize the loop gain equation to isolate A.
