Answer: The normalized corrected value at 32.5 mm = 0.69 mV
Explanation:
Signal value V1 = 20.7 mV at
distance value = 29 mm and
V2 = 15.8 mV is measured at 32.5 mm.
It is necessary, therefore, to subtract off this background level from the data to obtain a valid measurement
V1 = 20.7 - 5.1 = 15.6 mV
V2 = 15.8 - 5.1 = 10.7mV
The normalized corrected value at 32.5 mm will be
Vn = V2/V1 since V1 is the maximum value
Vn = 10.7/15.6 = 0.69 mV
