Abstract
Signal data is generated by interconnected non-inverting and inverting voltage followers and is transmitted on power-carrying conductors to a remote detection circuit comprising a differential amplifier which receives equal in-phase signal inputs of opposite polarity, thereby effecting cancellation of any externally-induced noise which might accompany the signal data.
