Repeat all parts of Problem 6.70 for the circuit of Figure P6.72 and the frequency response:
Let R1 = R2 = 1k?, C = 1?F, L = 1 H.
Use the same component values as in Problem 6.70.
Problem 6.70
For the circuit shown in Figure P6.70:
a. Determine the frequency response
b. Sketch, by hand, the associated Bode magnitude and phase plots. List all the steps in constructing the plot. Clearly show the break frequencies on the frequency axis. (Hint: Use the MatlabTM command “roots” or a calculator to quickly determine the polynomial roots.)
c. Use the MatlabTM command “Bode” to generate the same plots. Verify your sketch.
Assume
R1 = R2 = 2k?, L = 2 H, C1 = C2 = 2 mF.
