Abstract :
A method is presented to reduce the interference pickup in nerve cuff recordings. The gains of differential amplifiers connected to the true tripole nerve cuff arrangement are tuned adaptively to null the residual EMG. Simulation results show that extraction of the neural signal is possible using this method without the need for high order filtering
