SIMULATION PRACTICALS USING MULTISIM
Practical Simulation Objectives
After completing this practical simulation using Multisim, you should be able to
1. Analyse Differential Amplifier Circuit,
2. Design Differential Amplifier circuit,
3. Build and verify the behaviour of Differential Amplifier circuit in Multisim,
4. Compare the calculated (theoretical) values with the simulation results (measured values) obtained in Multisim.
The purpose of this practical simulation is to reinforce some of the more important properties and uses of Differential Amplifier. The readers should make themselves familiar with the properties of the Differential Amplifier. The behaviour of the Differential Amplifier will also be considered under certain conditions.
