This report focuses on the design and implementation of both wired and wireless systems to detect and analyze electromyography (EMG) and electrocardiogram (ECG) signals. The wired and wireless EMG systems were connected to a set of electrodes enclosures. The input signal is then processed through the front end of the system where it is amplified with a 50 V/V gain. The front end also delivers a common mode rejection ratio (CMRR) of 80–100 dB at 60 Hz, and 1 uV(rms) of noise over the passband. Similarly, the wireless ECG system followed the same design approach but had a gain of 25.7 V/V. The signal for the wired and wireless EMG is filtered at a passband of 15 - 800 Hz. The wireless ECG signal is filtered at a passband of 0.5 – 100 Hz. The wired EMG signal is connected to an ADC module through a USB communication cable. The wireless EMG and ECG systems transfer the signal data via Bluetooth LE using two microcontrollers that serve as an ADC module and Bluetooth central and peripheral devices. Using MATLAB, the signal data is then evaluated and utilized for other applications.
