to the input signal strength. In a nonlinear device, the output-to-input amplitude ratio (also called the gain) depends on the strength of the input signal. In an amplifier that exhibits nonlinearity,

the output-versus-input signal amplitude graph appears as a curved line over part or all of the input amplitude range. Two examples are shown below. The amplifier depicted by the red curve has gain that increases as the input signal strength increases; the amplifier depicted by the blue curve has gain that decreases as the input signal strength increases. Nonlinearity can be tolerated differential nonlinearity error in devices and systems that use digital modulation, and also in frequency modulation (FM) wireless transmitters. These signals are either full-on or full-off; the amplitude waveforms are not analog, so analog distortion cannot occur. In analog devices and systems, however, linearity is important. Nonlinear circuits generally cause distortion in applications such as amplitude-modulation (AM) wireless transmission and hi-fi audio.

Nonlinearity Error Definition
This tutorial is part of the National Instruments Measurement Fundamentals series. Each linearity error calculation tutorial in this series, will teach you a specific topic of common measurement applications, by explaining the theory and nonlinearity error equation giving practical examples. This tutorial will cover sensors and the terminology associated with them. For the complete list of tutorials, return to the NI Measurement Fundamentals Main page. Table of Contents Sensitivity http://whatis.techtarget.com/definition/nonlinearity Range Precision Resolution Accuracy Offset Linearity Hysteresis Response Time Dynamic Linearity 1. Sensitivity The sensitivity of the sensor is defined as the slope of the output characteristic curve (DY/DX in Figure 1) or, more generally, the minimum input of physical parameter that will create a detectable output change. In some sensors, the sensitivity is defined as the input parameter change required to produce a http://www.ni.com/white-paper/14860/en/ standardized output change. In others, it is defined as an output voltage change for a given change in input parameter. For example, a typical blood pressure transducer may have a sensitivity rating of 10 mV/V/mm Hg; that is, there will be a 10-mV output voltage for each volt of excitation potential and each mm Hg of applied pressure. Sensitivity Error The sensitivity error (shown as a dotted curve in Figure 1) is a departure from the ideal slope of the characteristic curve. For example, the pressure transducer discussed above may have an actual sensitivity of 7.8 mV/V/mm Hg instead of 10 mV/V/mm Hg. Back to Top 2. Range The range of the sensor is the maximum and minimum values of applied parameter that can be measured. For example, a given pressure sensor may have a range of -400 to +400 mm Hg. Alternatively, the positive and negative ranges often are unequal. For example, a certain medical blood pressure transducer is specified to have a minimum (vacuum) limit of -50 mm Hg (Ymin in Figure 1) and a maximum (pressure) limit of +450 mm Hg (Ymax in Figure 1).

Stefanski and Ciprian Crainiceanu July 2006 488 pages ISBN: 1584886331 CRC Web Site Information This book linearity error follows up on the authors' 1995 text on measurement error, but it is completely rewritten to have an emphasis on modern developments in the field. The book will replace the 1995 text as the integral nonlinearity error authoritative review of measurement error and uncertainties in exposures. The new book has many more data examples and incorporates of vast new literature written since 1995. "The authors have written a wonderful book.
