Duration 60 minutes QUESTION 1 [5/110] Who was thinking that muscles are activated by electricity? • The balloonists • Ancient Greeks • Luigi Galvani • Benjamin Franklin • Thomas Edison QUESTION 2 [10/110] This is the schematic representation of Hill model. Please describe briefly the nature of each lumped component. QUESTION 3 [10/110] Briefly explain the reason of the stochasticity of the EMG signal QUESTION 4 [5/110] Which of the following is an approximation of a polarizable electrode for measuring EMG? • Hydrogen electrode • Ag-AGCl electrode • Platinum electrode (inert metal) • Polarizable electrodes do not exist • Metal Electrode exchanging actual charges with the body QUESTION 5 [15/110] What does this schematic represent? What is the overall gain to differential and common mode at the leads + and -? What are the two main characteristics of this configuration with respect to the single amplifier in differential configuration? Please define the values of resistors for obtaining a gain of 402 in differential mode and 2 in common mode. QUESTION 6 [5/110] Which one of the following sentences is correct? • Forces are measured by using perfectly unreformable supports of strain gauges • Forces are generally measured by assessing the deformation they produce on a measurement interface • Measuring forces requires unreformable load cells • Force is preferably measured by wide deformation • As a general rule, deformation of metallic supports of piezoelectric crystals is not related to force exerted, it depends only upon the temperature QUESTION 7 [10/110] IEC 60601-1 standard uses the term applied part to…
