Discharging Capacitor Beginning at time t = 0, a capacitor of unknown value Cis discharged through a resistor R = 47 kN. What values are obtained for C and V? Does the best-fit curve accurately describe the V vs. Each element within the 2-dimension array of the S-matrix is a complex value where the row represents the frequency while the column represents time. The output of transformed voltage signal using ST is in the form of N × M matrix called S-matrix.
tfit as an interpolated line on the same XY Graph used to plot the V vs. LabVIEW MathScript node with user define function called S-transform output features. [11.26), that is, V fit = V exp (-tfit/RC), at all of the tfit values, Plot Vfit vs. Then create another array called Vfit, which is produced by evaluating the best-fit form of Eq. (9) Finally, generate an array of time values called tfit from t = 0 to 0.030 s in 0.001 s increments. Using these best-fit a, and 2, calculate C (in pF) and V, and display these values in front-panel indicators. These constants will be given as the first and second elements of the P row vector, that is, p(1) = 4, and p(2) = a, (unlike LabVIEW arrays, MathScript- array indexing begins with 1, rather than 0). s) = polyfit(x, y, 1) to determine the constants a.
Mathscript node labview code#
Add the required code within your MathScript Node to form the y array (use help basic to find the MathScript command for the natural logarithm), and then use [p. In particular, use the MathScript command can be linearized in the form of the first-order polynomial y = a + a,x, where a, and a, are constants. Discharging Capacitor (MathScript).vi (MathScript Only) Write a MathScript- based program that analyzes the discharging capacitor experiment described in Problem 6.
