Question

In comparison to ECG amplifiers, the surface-EMG amplifiers have

• A. A comparable gain and smaller bandwidth
• B. A comparable gain and larger bandwidth
• C. At least 20 dB higher gain and a larger bandwidth
• D. At least 20 dB lower gain and a smaller bandwidth

Hint:

EMG signals require amplifiers with larger bandwidths due to their higher frequency content compared to ECG signals.

Answer 1

The Correct Option is B

Surface-EMG (electromyography) signals involve higher-frequency components compared to ECG signals. Therefore, while the gain for surface-EMG amplifiers is similar to that for ECG amplifiers, the bandwidth is larger to accommodate the broader frequency range of the EMG signals. Hence, the correct answer is (B).
Final Answer: (B) A comparable gain and larger bandwidth
