Design any signal filtering system needed for your measurement system. Explain the need for the filters. Explain your thinking that informed your design. Calculate the error for this part of the measurement system.
You are a biokineticist and you want to develop a system to measure the electrical activity of muscle contractions (electromyography or EMG). The system will be a single-channel bipolar EMG system. You have purchased special EMG electrodes that will be placed onto the quadricep leg muscle. This is shown in Figure 1. You have obtained some sample EMG data from a colleague, which can be used to design the system. (You must generate this data based on your student number using Matlab code in Appendix A). The measured raw EMG data must be conditioned prior to transmission to a computer using a micro-controller. The system will always be used indoors, in a laboratory environment.
