Abstract
In this paper we present a passive impedance network that offers, to conventional QT configuration, the ability to null EMG interference without requiring tuning. The network is based on the Randles circuit model which fits the electrode- electrolyte impedance profile of our platinum electrode book, throughout the ENG band. The calculated RMS noise input voltage of the system was found to be 0.73 uV, thus making the solution plausible in terms of noise performance.
