Question

1. what type of frequency is blocked by an rl high pass filter?

a high
b low
c all
d none

Explanation:

A high - pass filter is designed to allow high - frequency signals to pass through while attenuating (blocking) low - frequency signals. The RL high - pass filter works based on the impedance characteristics of the inductor. The inductive reactance \(X_L = 2\pi fL\) (where \(f\) is the frequency and \(L\) is the inductance). At low frequencies, the inductive reactance is small, so the voltage across the inductor (which is related to the signal that is blocked in a high - pass filter configuration) is small. As the frequency increases, the inductive reactance increases.

Answer:

B. low
