<\/p>\nFigure 1\u00a0 \u00a0 \u00a0Schematic of Circuit Under Test (CUT) <\/strong><\/p>\n
Figure 1 shows the schematic of the circuit considered in this project. The circuit of interest is named Circuit Under Test (CUT) and has the following characteristics.<\/p>\n
- \n
- The CUT contains TWO<\/strong> circuit elements only: Element X and Element Y.<\/li>\n
- The two circuit elements are connected in series.<\/li>\n
- Both Element X and Element Y can be a resistor, inductor or capacitor.<\/li>\n
- The CUT must contain at least one resistor. This means that the circuit of interest can be a RR, RL or RC circuit only.<\/li>\n<\/ul>\n
At the start of a lab session, each group will be given a CUT that contains randomly chosen element type and value. With the CUT concealed<\/strong> in a box, your group is tasked with the challenge to achieve the following four objectives by the end of your lab session.<\/p>\n
- \n
- Identify the type of element that is connected between node A and node C. In other words, determine if Element X is a resistor, inductor or capacitor.<\/li>\n
- Determine the value for Element X. The predicted value must fall within \\pm 20\\% <\/span> of the actual component value.<\/li>\n
- Identify the type of element that is connected between node B and node C. In other words, determine if Element Y is a resistor, inductor or capacitor.<\/li>\n
- Determine the value for Element Y. The predicted value must fall within \\pm 20\\% <\/span> of the actual component value.<\/li>\n<\/ul>\n
The grades earned in this first category of assessment depend highly on your success in achieving the four objectives described above. The weighted grading scheme is as follows:<\/p>\n

Violation of any of the following rules will result in penalty detailed in Table 3 below.<\/p>\n
- \n
- Rule #1:<\/strong> You are NOT<\/strong> allowed to unveil the CUT concealed in a box to help you achieve any of the four objectives described above.<\/li>\n
- Rule #2:<\/strong> You are NOT<\/strong> allowed to use the resistance measuring function on any instrument including digital multimeter (DMM), LCR meter, etc. to measure directly the resistance of any circuit element.<\/li>\n
- Rule #3:<\/strong> You are NOT<\/strong> allowed to use the capacitance measuring function on any instrument including digital multimeter (DMM), LCR meter, etc. to measure directly the capacitance of any circuit element.<\/li>\n
- Rule #4:<\/strong> You are NOT<\/strong> allowed to use the inductance measuring function on any instrument including digital multimeter (DMM), LCR meter, etc. to measure directly the inductance of any circuit element.<\/li>\n
- Rule #5:<\/strong> For any input that you apply to the CUT, the input can only be connected between node A and node B. In other words, you are NOT<\/strong> allowed to apply any input between node A and node C as well as between node B and node C.<\/li>\n
- You are allowed to take voltage and current measurement at any node.<\/li>\n
- You are allowed to connect any circuit element externally to the CUT concealed in a box.<\/li>\n<\/ul>\n

- \n
- WARNING: If you unveil the CUT concealed in a box to help you achieve any of the four objectives described above, you will earn a grade of zero for this specific project regardless of how much work you have completed. Penalty for the violation of Rule #1 will be strictly enforced.<\/strong><\/li>\n
- WARNING:<\/strong> Pay attention to all the rules and penalties described above. Please understand that the penalties are not created to destroy your grade; they are established for the sole purpose of ensuring fairness among all students who work on this project.<\/li>\n
- Collaborations between any groups are strictly prohibited in this project.<\/li>\n<\/ul>\n
TECHNICAL NOTES:<\/strong><\/p>\n
- \n
- WARNING:<\/strong> If you use a DC power supply, be mindful of the current setting on the equipment to avoid undesirable incident.<\/li>\n
- Frequency response higher than 500 kHz will not be considered in this project.<\/li>\n<\/ul>\n
II. Demo<\/h3>\n
Perform the following tasks.<\/p>\n
- \n
- Provide the element type and value you have predicted for both Element X and Element Y to your Lab TA.<\/li>\n
- Demonstrate to your Lab TA how you have arrived at your conclusions. Provide detailed explanations and reasonings on how you have obtained the results during your demo.<\/li>\n
- Record down your results for the writing of your report.<\/li>\n<\/ul>\n

- \n
- All project demonstrations must be performed during a lab session. No project demonstration can be performed outside lab session.<\/li>\n
- All groups will be given only ONE<\/strong> lab session to demonstrate the accomplishment of the objectives described above.<\/li>\n
- HEADS UP:<\/strong> It is impossible to develop a working plan in a 2-hour lab session. To prepare fully for your project execution and demonstration, you are highly encouraged to perform circuit simulations and experiments at home so that you can figure out a plan for your project. To perform experiments outside of the laboratory, you can loan out a Hantek 3-in-1 digital equipment and a powered breadboard. You can also acquire circuit components from the laboratory, and they are not required to be returned.<\/li>\n
- SUGGESTION:<\/strong> You are strongly encouraged to complete the following tasks prior to your lab session.\n
- \n
- Establish an experimental plan to identify the type of circuit element. Elimination of possibilities can be a good strategy here. <\/li>\n
- Establish an experimental plan to determine the value of circuit element.<\/li>\n<\/ul>\n<\/ul>\n
III. Report<\/h3>\n
