Linearity 1
Linearity 1 : Amplitude: The characteristic of an ultrasonic testing system indicating its ability to respond in a proportional manner to a range of echo amplitudes produced by specified reflectors. Distance: The characteristic of an ultrasonic testing system indicting its ability to respond in a proportional manner to a range of echo signals, produced by specified reflectors, variable in time, usually a series of multiple back reflections.
