Question

-If the input voltage increases to 50 V in Figure 10 -3, what is the output voltage at the cutoff frequency?
A)35.4 V 
B)17.7 V 
C)70.7 V 
D)8.84 V

Quizplus · Accepted Answer

At the cutoff frequency, the output voltage is typically 70.7% of the input voltage for a first-order low-pass filter. Therefore, 70.7% of 50 V is 35.35 V, which rounds to 35.4 V.
