## Description

Circuit Analysis – Week #6 Lab

Laplace Transform and Analysis in S-Domain

This week’s lab is based on the application of circuit analysis techniques to a capacitive circuit with Multisim. You will learn to utilize Multisim to perform the mesh analysis.

1. See file “Design of Oscillator Circuits” (click link)

2. Design a Wein bridge Oscillator shown in the figure below in Multisim to generate a sinusoidal signal at frequency of 300Hz. Consider a capacitor of 1uF, resistor R = 5950Ω, R1 = 3Ω, Rf = 6.05Ω for the oscillator circuit.

a. Determine output voltage ‘Vo’ and run the simulation to plot the output of the oscillations at frequency of 300 Hz using an oscilloscope.

b. Increase the frequency to 500Hz, 800Hz and 1000Hz and plot the output of the oscillator at these multiple frequencies.

c. Take the screen capture of the oscilloscope readings for all the frequencies.

3. Answer the following questions:

a. What is the requirement to generate oscillation in the circuit? Is the circuit stable or unstable?

b. What do you observe in the oscillations when the frequency is increased?

c. With increased frequency, did you observe the oscillations? If not what did you adjust to observe the oscillations?

d. Explore different practical applications of oscillator circuits and explain.

4. Create a new word document called “Lab6_StudentID.docx” with your GID substituted into the file name.

Introduction

The purpose of this lab is to apply circuit analysis techniques to design a Wein bridge Oscillator

in Multisim. Sinusoidal waves of different frequencies are generated and viewed through

oscilloscope.

Equipment:

The circuit is implemented in Multisim consisting of resistors, capacitors, power sources,

OPAMP and an oscillator. Two power sources of 12VSS and -12VDD is used along with 4

resistors and 2 capacitors. The OPAM...
