In systems theory, a linear system is a mathematical model of a system based on the use of a linear operator. ![]() JSTOR ( June 2021) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed. Please help improve this article by adding citations to reliable sources. Also you should take notes on how you will build the circuits in the EE Board before the actual assembly in the laboratory class.This article needs additional citations for verification. All the circuits must be hand drawn in the laboratory notebook, where they must be solved analytically and then simulated in Multisim. This is necessary for the effectiveness and efficiency of the procedures carried out in this laboratory. 4- In order to have a better understanding and to be acquainted with all the procedures of this laboratory, all the members of each laboratory group must read and familiarize with these experiments before entering to the laboratory class. Complete Table 3.1 by calculating the values of VA, I1, 12, and 13 when both Vs and Vs2 are active. Note that VAI is the component of VA due to Vsi, and VA2 is the component of VA due to Vs2. 2- Use the Superposition principle to calculate the components of V, 11, 12 and 13 due to each source acting alone, and record your results in the table of calculated data, Table 3.1. Make sure that the instructor reviews your analysis and simulation before proceeding with the experiment. PRE-LABORATORY 1- Perform the analysis and simulation of the circuit shown in Figure 3.1 before entering to the lab. ![]() Also, pay attention to the directions of the current components due to each source, so that you algebraically add them correctly in order to obtain the correct results. It is important to note that, in practice, you must remove the power supply before you replace it with a short: NEVER short-circuit a functioning power supply under these circumstances. BME 3221 - Electric Circuits and Electronics Laboratory Manual This is the same as replacing the voltage sources with short circuits and the current sources with open circuits. You will recall that the source not being considered is to be killed or replaced with its internal resistance. IR1 Node IR3 R1 1.5k TR2 1ka Vs2 Vs1 8V 4760 3 5V Figure 3.1: Circuit to be implemented in the laboratory to verify the Superposition Theorem The node voltage VA and the currents 11, 12, and I can be calculated by taking the components due to Vsi acting alone, then the components due to Vsz acting alone, and finally adding them together. This experiment uses a circuit with two voltage sources: Vsi and Vs2 (see Figure 3.1). Particular attention must be paid to current directions and voltage polarities when applying superposition. BACKGROUND: The Superposition Principle allows us to calculate the combined effects of any multi-source linear circuit by looking at the individual effects of each source acting alone, then summing them.
