Question: Suppose that we need a first-order RL low-pass filter that reduces the amplitude of a component at a frequency of 100 kHz by 50 dB.
Suppose that we need a first-order RL low-pass filter that reduces the amplitude of a component at a frequency of 100 kHz by 50 dB. The resistance is to be 2.2 k12. Find the half-power frequency and the inductance. Using the semi-logarithmic graph below, plot the Bode plots for this circuit.
