AC mode indicates that a high-pass (HP) filter has been applied to the signal that you are recording. An HP filter removes the low-frequency components of a signal. The most common AC mode settings on BIOPAC amplifiers are 0.5 Hz HP and 0.05 Hz HP. In AC mode, the signal is centered around zero.
AC mode is useful in studying changes in the signal. AC mode is not appropriate for recording absolute measures or for detecting the baseline level of the signal.
New series of unshielded 45 cm electrode leads with thin cable; suitable for facial EMG and other areas where lighter, shorter lead cables are required. Use for female Touchproof connectors to pinch clip connectors—connect electrodes to either a C-series amplifier or an MEC. The pinch connectors are light weight and the lead cable tinsel wire […]
