Question 1
What is the cutoff frequency of a filter?
Question 2
In a first-order low-pass filter, what is the typical roll-off rate?
Question 3
How does increasing the capacitance in an RC low-pass filter affect its cutoff frequency?
Question 4
What is the primary advantage of using an active filter over a passive filter?
Question 5
If a band-pass filter has a center frequency of $1 \text{ kHz}$ and a bandwidth of $200 \text{ Hz}$, what are its lower and upper cutoff frequencies?
