What Is Linearity Error
is 4.277 mV and at 200T it is 9.286 mV. If a linear relationship is assumed between e.m.f. and temperature over the fiill range, the non-linearity error at 100°C is: the answer is -7.9°C but how??????????

T(EMF) = A + B*EMF + C*(EMF^2) Recall in mathematics that for a system of equation to have a unique solution, the number of equations must have the same number of unknowns. By substituting the values in (1), (2), and (3), we get three equations that enable us to solve for the three unknown coefficients A, B, and C in (4). For example, substituting (1) in (4), we get A = 0 , so that (4) reduces to (5) ..... T(EMF) = B*EMF + C*(EMF^2) Subs
deviation of the output signal from an ideal straight line (at least for a linear device). To measure the non-linearity one should obtain the output data of the imager for a range of know exposure levels. These can be generated linearity calculation worksheet xls by means of : - using a changing light source at a fixed integration nonlinearity error potentiometer or exposure time, - using a fixed light source, but change the integration or exposure time of the sensor. Other simple tricks
Linearity Error Excel
to change the amount of light to the sensor, is to create a smear signal in frame-transfer and full-frame CCDs. Just before a frame is being readout, it is first reset so that no actual video data https://answers.yahoo.com/question/?qid=20100402103439AAo52zx is contained in the sensor. After the reset, the sensor is being readout with light shining on it. In this way the output signal is composed only out of smear. And the smear is constantly increasing from line to line. In this way a variable light input is created from line to line. A similar effect can be obtained in a 3T or 4T CMOS pixel : after a global reset of the http://harvestimaging.com/blog/?p=1125 pixels, the sensor is immediately read out in a rolling shutter mode. Note that in these two situations, a uniform illumination of the sensor is needed. To measure the linearity of the pixels, it should be clear that a light source is needed that is stable over time, and does not change its colour temperature. In the measurements that will be reported here, a fixed light source is used, based on a small LED backlight illumination, and the amount of photons coming to the sensor is changed by manipulating the exposure time. Next question that needs to be answered : how is the non-linearity defined and calculated ? And here a distinction is made between the integral non-linearity and the differential non-linearity. Integral non-linearity (INL). The integral non-linearity is described as the deviation of an actual transfer function from a straight line. The definition is depicted in the illustration below : The following curves are being shown in the figure : - the ideal transfer curve, - the actual transfer curve, linking the output of the sensor to its input, - the best straight line fit through the actual transfer curve. As can be seen from the figure, the best straight line fit to the actual transfer curve runs in parallel to the ideal transfer curve, but both lines not necessarily pass thro

I know it should be an iterative method, but I don't know what would be the best method to use. Any help is highly appreciated. erf(x) + a*x = b ; where both a and b are constants.

If so, simply use Newton's method and iterate $$ n(x) = x - \frac{f(x)}{f'(x)} = x-\frac{a x-b+\text{erf}(x)}{a+\frac{2 e^{-x^2}}{\sqrt{\pi }}} $$ For example, if $a=2$ and $b=1$, then starting at $x=1.0$, you'll generate the sequence $$1.0, 0.237011, 0.322921, 0.323604, 0.323604.$$ Alternatively, if you've just got a few cases to solve, you could enter it into WolframAlpha: share|cite|improve this answer answered Mar 28 '13 at 20:25 Mark McClure 18.1k2954 Thanks a lot Mark. Can I extend my question like this: What if x is now a vector of (N by 1) and A is a matrix of (N by N) and b is also a vector of (N by 1). This follows the non-linear equation: erf(x) + Ax = b I am confused in isolating the term x from the combined term Ax so that I can apply Newton's method on this. Any ideas? Thanks again for your prompt reply. –kasun61 Mar 28 '13 at 20:53 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
