Objectives and Tasks - The ultimate goal of the project is to identify the circuit elements used in a given circuit. - To achieve the design requirements, our group needed good understanding of filters. Dissection of Implementation To identify the Element X and element Y described below, the group needed a good understanding of the low pass filter and high pass filter and what that would translate by which element would have voltage (also varying depending on voltage frequency) and current. Since there were only two elements on the circuit, we first used the digital multimeter to find the voltage across each component. The voltage across our Element Y was essentially 0 and the voltage across Element X was the entire voltage. When we measured the current from Element X we found it to be like the images below. After finding out that the circuit was a High Pass filter, we implemented AC voltage on the circuit, and we kept increasing the frequency until we reached 0.707 of the source voltage which is our cut off frequency. We used the voltage divided by the current to find the Resistor Value. Then, we used the equation Wc= R/L. Since we know the cut off frequency and resistance, we can simply solve for the inductance.

Results Comparison Our physical measurements perfectly matched our calculation and implementation of our circuit on Multisim. We indeed had a High Pass filter with Resistance of 9100 ohms and inductor of 100 mH. We arrived at these numbers by calculating the voltage and current on each element, then figuring out what happened as frequency changed. Then we used calculation to find Resistance and the inductor values. Conclusion In summary, our success in meeting the requirements outlined in the prompt can be attributed to meticulous calculations of key parameters such cutoff frequency, Resistor value and Inductor Value. We needed to implement our understanding of which single element performs according to different types of filters and what each filter does. By our observations we were able to detect the type of filter, the elements that were used and the values of each element in order to match our recordings from the multimeter
