Question 1.
What happens to the gain when two amplifiers are cascaded?
Show hintHide hint
Think about what happens when an output connects to an input.
Question 2.
Define a buffer in the context of amplifiers.
Show hintHide hint
Consider its role in managing signals.
3Question 3.
What is the impact of loading effects when cascading amplifiers?
- Increase in gain
- Decrease in gain
- No effect
- Increase in cutoff frequency
Show hintHide hint
Remember the voltage division concept.
4Question 4.
Is it beneficial to use buffers between amplifiers?
- True
