The objective of this problem is to examine the features in PSpice that simulate a circuit as its input frequency is varies, allowing to characterize the frequency response of the circuit. The frequency response of a circuit can simulated in PSpice using OrCAD Lite using AC Sweep analysis. The frequency can be varied linearly or logarithmically (decade or octave). 1. Refer to the circuit diagram in Figure 1, analyse the circuit qualitatively to determine the circuit behaviour as a filter. Support your analysis quantitatively by finding the transfer function of the filter. Find the expressions for the centre frequency wo, cutoff frequencies wcl and wc2, bandwidth B, and quality factor Q of the filter. R w Figure 1: RLC Circuit

2. If the input voltage source viis 250 cos Wot mV, and the numerical values for R, C, and L are as shown in Figure 2. Find the numerical values for the centre frequency fo, the bandwidth B, and the quality factor of the filter. 100 k12 200 pF 5 mHV. Figure 2: RLC Circuit With Given Values 3. In PSpice, Use Probe to plot vo versus f in the range of fo£40 kHz in increments of 1 Hz on a linear frequency scale. 4. From the Probe plot, use the two cursors to estimate the centre frequency fo, the bandwidth B, and the quality factor Q. Compare the results obtained with the analytical solution in step (2).
