Explain the effect of electrodes in localized EMG measurements.
Provide a non-invasive technique for measurement and detection of EMG signals.
They form a chemical equilibrium between the detecting surface and the skin of the body through electrolytic conduction.
So that current can flow into the electrode.
The first-order filters are not used in the processing stages of ECG systems because:
a. They do not provide enough attenuations.
b. They do not give exact cutoff frequency.
c. They do not provide accurate passband.
