Question

If the value of the feedback resistor in the filter is changed but the value of the resistor in the forward path is unchanged, what characteristic of the filter is changed?

Answer 1

Answer:

The cut off frequency and the  passband gain will change

Explanation:

Answer :

Since the cut off frequency ω and the passband gain K are the function of the feedback of the resistor R2, Both K  and ω will change.
