The patient cable introduces analog microvolt-level signals through a defibrillator protection resistor network. The Right Leg Drive (RLD) circuit actively cancels common-mode noise and 50/60Hz power line interference. Signals pass through an instrumentation amplifier before entering the 12-bit A/D converter. Main Control Board
Floating; features protection against defibrillators and pacemakers. A/D Converter: 12-bit. Frequency Response: 0.05Hz to 150Hz.
