Introduction
In this final project, which spans the last 4 lab sessions of the semester, you will design, simulate and build a complete tone-control/Karaoke circuit according to the specifications in this document. While this circuit will be larger than anything you have designed before in this EE 210 lab, you will find that the various blocks that comprise this project are either identical to or very similar to circuits that you have already built. In some cases, you may be able to use the exact circuit topologies you have designed before. In other cases, slight modifications may be necessary. You may consult with your lab partner on the design, but each student must write up the design in their own lab notebook, do their own simulation and build/demonstrate their own project.
This Final Project is worth 40 points – about 26.67% of your EE 210 lab grade and 6.67% of your entire EE 210 course grade. Project Components: Design, Simulation, Prototyping, Testing, Soldering, Demo, Formal Report Lab session 12: Your first task will be to design the complete project (block by block) meticulously in your lab notebook, and then produce a working Multisim model of the entire project. You should be able to design each of the 5 blocks based on your prior lab experiences. As you design each block in your notebook, build the block in Multisim, attaching it to the prior block(s) as needed. We recommend that you demonstrate each block to your TA as soon as you design/simulate it to verify that it is correct. This will avoid headaches later on. When you are done, you will have a complete Multisim schematic of the entire project.
Lab sessions 12-13: Once your simulation is working properly, you will build a prototype circuit on your breadboard and test its operation. There are some audio files in Canvas that you can use to test your project. These particular files have been selected because the Karaoke function works particularly well with them. You may find other songs that also work well. As you build/test your circuit you may want to alter some of the component values to tweak the performance of your circuit.
Once you are satisfied with the performance, you will demo it for your TA. You will be asked to input a signal to your project and demonstrate all circuitfunctions. You may also be asked to display certain block inputs and outputs on the oscilloscope, so make sure that you know where the inputs and outputs to each block are on your breadboard circuit.
Lab session 14-15: The final part of this project is to solder your project onto a printed circuit board (PCB) provided in your lab kit. A circuit diagram will be given to you prior to week 14 as a guide. Once you solder your project, you will once again demo it to your TA. All circuit functions need to work to get full credit.Formal Report: You will submit a formal report (complete with your Multisim simulations) as part of your final project. Read the formal report details later in this document.
