Question

Consider the circuit below:

Circuits 2 Lab Homework, Due Lab 13 Consider the circuit below. The source is a 1 Amp sinusoidal current source. As such, the phasor voltage Vab across the terminals a & b is simply 1 times the impedance Zab. clean sheet of paper and in a neat and orderly fashion, do the following: 1. Derive an equation for Zabls) in terms of the component names R1, L, C, and R2. (See Hints) 2. Find the poles and zeroes of Zab(s) by substitute component values into your equation and Put a box around your equation for Zab(s). solving for the roots of the denominator and numerator respectively. Put a box around your poles and zeros. Hints for calculating Zab(s), See figure below: .Calculate Zoac(s) first. That is, the impedance of Zc(s) in parallel with R2. Calculate Za-c(s) next. That is, the impedance of Zu(s) in series with Zacds). Now calculate Zab(s). That is the impedance of R1 in parallel with Zunac(s). You should end up with second order Numerator and Denominator polynomials. Zab R2 R1 1 ZL-R2-C
