ELECTRONICS DEVICES AND CIRCUIT

Since the average voltage across the inductor is zero, we can write the following: VS−VaDT −VaD1T = 0 5.16 Rearranging of terms we have the duration of inductor current discharging D1T =[r]

6. Make sure the loop has sufficient voltage to drive the input. D. DISCRETE INPUTS Discrete inputs provide a similar value, and are used in the same way as analoginputs, primarily for turnkey type systems. One of the most useful is a backwashvalve position indicator. This is tied to a dry con[r]

The variables x1, y1, x2, y2, etc., are pairs of vector. Each x-y pair is graphed, generating multiple lines on the plot. The above plot command allows vectors of different lengths to be displayed on the same graph. MATLAB automatically scales the plots. Also, the plot remains as the current plot un[r]
