When on-line averaging is invoked, some signal amplitude excursions may need to be excluded during the averaging process. Artifact Rejection is a feature for just this purpose. When artifact rejection is enabled, the MP150 System will ignore any trials that contain signals exceeding the artifact rejection thresholds, keep track of how many trials have been rejected, and add that number of trials to the total number of trials to be acquired. This allows users to “re-try” a trial that was rejected due to the presence of artifact.
Occasionally during an acquisition, extreme levels of artifact will be present for one reason or another. Checking artifact rejection allows users to determine what signal levels constitute artifact, and have the MP150 System reject these trials.
This application note provides a procedure/test case to confirm that AcqKnowledgeArtifact Rejection is functioning properly.
Easily record great ECG data and derived signals for heart rate, RR interval, and R-wave amplitude. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact. AcqKnowledge Smart […]
BIOPAC provides researchers with a complete range of tools to gather data on heart rate variability (HRV). The following studies demonstrate just some of the ways in which HRV research benefits from the implementation of BIOPAC hardware and software solutions. PTSD and HRV Post-traumatic stress disorder (PTSD) has been associated with dysfunction of the autonomic […]
