3. The frequency response magnitude plot for a particular circuit is shown in Figure 3 below, with XdB = 65 dB, 1 = 1 krps, and co2 = 250 krps. Note that the slope labeled in the figure is -40 dB/dec. |H|, dB XdB 0 dB YdB W1 Wx slope = -40 dB/dec W2 Figure 3. Frequency response magnitude for Problem 3. work: log w Answer the following, and show your a) Determine the numerical value of ox, which is the angular frequency at which the frequency response magnitude makes a crossing at 0 dB. Include appropriate units with your numerical answer in proper engineering notation format. b) Determine the numerical value of YdB, which is the frequency response magnitude at high frequencies. Include appropriate units with your numerical answer in proper engineering notation format. c) Based on the frequency response magnitude in Figure 3, determine a plausible transfer function H(s), which approximately (this is key; do not overcomplicate this!) yields the same frequency response magnitude as that shown in Figure 3. Write your transfer function in proper Bode approximation format. Note that "s" should be the only variable in your expression; all other terms in your transfer function H(s) should be numerical, and should be listed in proper engineering notation format.
