The purpose of this lab is to experimentally construct the frequency responses of two circuits. The circuits to be studied are the passive RLC circuit shown in figure 1 and the active network shown in figure 2.

1. Frequency response of RLC circuit.

- Construct the circuit shown in figure 1.
- Let
*v*be a 1 V_{in}(t)_{p-p}sine wave for which you'll vary the frequency. - Use your prelab results as a guide as to what frequency range should be
used and measure the frequency response (magnitude and phase) of
*V*/_{out}(jw)*V*. Note the function generator and oscilloscope display frequency in Hertz and your Bode plots are likely versus frequency in rad/sec, so make sure to convert whichever way you choose to keep the units consistent. Take extra points in regions where the magnitude or phase change quickly._{in}(jw) - Compare your results with the calculated values plotted in the prelab by recording the experimental data on top of the calculated prelab data.
- How would one describe this circuit?
- Does this passive circuit ever yield a gain larger than 1 (0dB)? If so, how is this possible?

2. Frequency response of active circuit.

- Construct the circuit shown in figure 2.
- Let
*v*be a 1 V_{in}(t)_{p-p}sine wave for which you'll vary the frequency. - Use your prelab results as a guide to what frequency range should be used
and measure the frequency response (magnitude and phase) of
*V*/_{out}(jw)*V*. Note the function generator and oscilloscope display frequency in Hertz and your Bode plot is likely versus frequency in rad/sec, so make sure to convert whichever way you choose to keep the units consistent.
