Abstract: According to one aspect of the present disclosure, an electromyography (EMG) circuit comprises a difference circuit, rectification circuit, offset removal circuit, and integration circuit. The difference circuit is configured to create an EMG signal based on a difference between two action potential voltages. Creation of the EMG signal introduces a voltage offset, not already present in the action potential voltages, that centers the EMG signal about a non-zero voltage. The rectification circuit is connected to the difference circuit and is configured to rectify the EMG signal about the non-zero voltage to create a rectified EMG signal. The offset removal circuit is configured to remove the voltage offset from the rectified EMG signal to create an adjusted EMG signal. The integration circuit is connected to the offset removal circuit and is configured to integrate the adjusted EMG signal to produce a first EMG output signal for a client device.
