Question

Which of the following two elements are removed by the detection filter in the process of the ECG waveform?

(a) Low frequency noise, motion noise

(b) Muscle artifact, motion noise

(c) Baseline wander, motion noise

(d) Baseline wander, muscle artifact

The question was posed to me in exam.

My question is taken from Clinical Data Interchange/Exchange Standards in section Telemedicine Technology of Biomedical Instrumentation

Answer 1

Correct option is (a) Low frequency noise, motion noise

To elaborate: The detection filter removes low frequency noise (baseline wander) and muscle artifact. The ECG waveform is processed by two digital filters: a detection filter and a classification filter.  P waves and T waves are diminished.
