Filter Consists Of

Answer: A. 125 Hz

An RL high-pass filter consists of a 470 Ω resistor and a 600 mH coil. The output is taken across the coil. The circuit’s critical frequency is 125 Hz.

Solution

Filter consists of-

Resistor (R) = 470 Ω

Inductance (L) = 600 mH

At critical frequency,

X_L=R

2fπL=R

f=R/2πL

f=470/(2×π×600×10^-3)

f=125 Hz
