Question 1.
What do we expect the overall gain to be when cascading two identical CE amplifiers?
Show hintHide hint
Remember the formula for gain in cascaded systems.
Question 2.
What alteration occurs in the frequency response of cascaded amplifiers?
Show hintHide hint
Think of loading effects and frequency response definition.
3Question 3.
What is the expected overall gain when cascading two amplifiers with gains of 5 each?
- 5
- 10
- 25
Show hintHide hint
Think of multiplication of gains in cascading.
4Question 4.
True or False: Cascading amplifiers always leads to an increase in bandwidth.
- True
- False
Show hintHide hint
Reflect if cascading changes inputs.
Question 5.
Explain how using a buffer can virtually eliminate gain attenuation while cascading amplifiers.
Show hintHide hint
Focus on the principles of impedance and load effects.
Question 6.
Given two amplifiers with gains of 12 and 8, and a loading resistance of 3kΩ from the first to the second, calculate the actual output voltage if the first stage outputs 2V.
Show hintHide hint
Use voltage division principles to apply the loading effect.
