Question 1

What is the total gain formula for a cascaded amplifier?

A_{V(total)} = A_{V1} + A_{V2}
A_{V(total)} = A_{V1} × A_{V2}
A_{V(total)} = A_{V1} - A_{V2}

💡 Hint: Think of how gains are combined.

Question 2

A ladder filter primarily consists of what elements?

True
False

💡 Hint: Recall the definition of ladder filters.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a cascaded amplifier consisting of three stages. If the individual gains are 2, 3, and 4, find the overall gain and then explain how it would change if one of the stages had a gain of 0.5.

💡 Hint: Keep track of how each stage affects the overall gain.

Challenge 2 Hard

Compute the ABCD parameters for a ladder filter composed of an inductor (1H) and two capacitors (100uF each). Use the known parameters for each component and perform the multiplication to find the total.

💡 Hint: Make sure to perform matrix multiplication correctly to achieve the final parameters.
