* Noise rejection is the ability to reject unwanted signals, or noise.
• Normal mode voltages are AC signals that can cause inaccurate DC measurements.
NMRR (Normal Mode Rejection Ratio) is a measure of the ability to filter out these
signals.
• Common mode voltages are signals present at the COM and + input terminals, with
respect to ground, that can cause digit rattle or offset in voltage measurements. CMRR
(Common Mode Rejection Ratio) is a measure of the ability to filter out these signals.
