Lab 7 (continuation of lab 6): interfacing circuit for sensors/biopotential electrodes - biomedical signal amplification (part 2) lab preparation: design the circuit of each amplifier, including the values of all the components. explain why these values are selected. in many real-world tasks, such as implementing the interfacing circuit for biomedical sensors/biopotential electrodes, engineers need to amplify biomedical signals in desired ways. this lab session is a practice of how to design amplifiers using op-amps according to application requirements. parts: resistors, capacitors, op-amps, jump wires, multimeter, function generator, oscilloscope, and other devices available based on the students' requests. tasks: use function generator to simulate two biomedical ac signals s1 and s2. the magnitude of s1 should be 1v (magnitude), and the frequency of s1 equals 50 hz. the magnitude of s2 should be 2v (magnitude), and the frequency of s2 equals 50 hz. design op-amp circuits to implement the following signal processing: 1. output a signal equals: - 551 - 4s2. 2. output a signal equals: 252 – 351 lab report: for each signal processing task: 1. draw the circuit, mark the values of each circuit component, and give rationales to explain why these components values are selected. if you used the same design as that in your lab preparation, you can simply claim this in your report without duplicating the content. 2. write down steps of the experiment, present pictures of the real connected circuits on board, and present pictures of the output signal.
