![]() You can press AUTO-SET on the oscilloscope face (upper right) and it will try to pick the best settings.If the max value is 30, what will the function described in equation \eqref)įirst connect the signal generator directly to the oscilloscope as shown.Ĭreate a 100 Hz square wave on the signal generator and make sure you can see the signal on the oscilloscope. Specifically, $\tau$ is the time required to reach 63% of the max value. Large time constants however, mean the function takes a longer time to reach the maximum value. Here is an interactive plot you can adjust $\tau$ on and see the effects.Īs you can see, a small value of $\tau$ means the function quickly reaches a maximum. ![]() ![]() The constant $\tau$ is called the time constant and its value will determine the how quickly the value of y reached its asymptotic maximum. Here, $t$ is the variable for time, and $y$ represents some value that is changing as a function of time. If not, check again, then talk to your lab instructor.įirst, let's understand the plot of a function that looks like this: Please make sure your station has all of the following items. In this lab you will observe how a capacitor can be charged and discharged and determine the values of a resistor and capacitor using the oscilloscope. Lab Instructor = please log in Introduction
