Question

____________  is the sampling rate of analog-to-digital converter in digitizing of ECG signal in signal conditioning.

(a) 200-215 Hz

(b) 215 Hz

(c) 40-100 Hz

(d) 250 Hz

Answer 1

Right choice is (d) 250 Hz

For explanation I would say: In signal conditioning, ECG signal is amplified, filtered (0.05-100 Hz for diagnostic purposes, 1-40 Hz for monitoring purposes) and digitized using an 8- or 12-bit analog-to-digital converter with a typical sampling rate of 250 Hz.
