- Electromyography (EMG)
(a)  Consider the techniqueof electromyography (EMG) to examine muscle function about jointsduring movement. Explain where the captured, high frequency rawsignal originates, and describe the physiological basis withreference to the relevant parts of the neuromuscularsystem.                                                                                         [8marks]
(b) When processing EMG signals, thefollowing terms are frequently encountered in the literature:
(i) Band Pass filtering
(ii) Full wave rectification
(iii) Normalisation to maximumvoluntary contraction (MVC)
(iv) Median frequency
Please explain what each of these terms mean, and describe theirrelevance/role in the context of interpretingEMG.               Â
