(c) (d) The signal from a transducer is used as the input to a signal conditioning circuit which has the response shown in the equation below, where x is the input and v is the conditioned output. The output from the signal conditioner is found to be very noisy and direct measurements of x and v are made to identify the problem. These results are shown in table Q1 below. On analysis, the fractional uncertainty in v is estimated to be v/v = ± 0.25. Linearise this equation and express it in the form, "y =mx+c". Treating your expression for "y" as a function of one variable, find the uncertainty in this expression. [3] Plot a linear graph of these results and visually estimate the best fit line to the data.
