Question

EMG instrument contain frequency component extending up to ____________ Khz.

(a) 1

(b) 5

(c) 10

(d) 15

I had been asked this question during an internship interview.

I would like to ask this question from Measurement of Respiration Rate topic in section Patient Monitoring System of Biomedical Instrumentation

Answer 1

The correct answer is:

(c) 10

EMG (electromyography) instruments typically measure electrical activity produced by muscles and the frequency components in EMG signals extend up to around 10 kHz. These signals typically fall within a range of about 10 Hz to 10 kHz, depending on the type of muscle activity being measured.
