In the process of the ECG waveform, the detection filter removes _____

1.	In the process of the ECG waveform, the detection filter removes _______ and _______(a) Baseline wander, motion noise(b) Muscle artifact, motion noise(c) Low frequency noise, motion noise(d) Baseline wander, muscle artifactThe question was asked during an online interview.This interesting question is from Phonocardiography (PCG) topic in division Biomedical Recorders of Biomedical Instrumentation
Answer» Right CHOICE is (c) Low FREQUENCY noise, MOTION noise To elaborate: The ECG waveform is processed by two DIGITAL filters: a detection FILTER and a classification filter. The detection filter removes low frequency noise (baseline wander) and muscle artifact. P waves and T waves are diminished.
