Using a 4 mH inductor, design a high-pass, RL, passive filter with a cutoff frequency of 27 krad/s. Part APart complete Specify the value of the resistance. Express your answer to three significant figures and include the appropriate units. R = 108 Ω Previous Answers Correct Part B Assume the filter is connected to a pure resistive load. The cutoff frequency is not to drop below 24 krad/s. What is the smallest load resistor that can be connected across the output terminals of the filter?

    Rl≤ 864 ohms

    Explanation:

    ω=2πf⇒ f=ω/2π

    ω=27000

    fc=R/2πL

    27000/2π = R / (2π*0.004)

    R=108 ohms

    For terminated RL filters, cutoff frequency is given by

    ω = (R || Rl) / L

    24000 ≥ (108 || Rl) / 0.004

    96 ≥ 108Rl / (108+Rl)

    Rl≤ 864 ohms
