In this experiment, the output of a frequency generator was observed on the screen of an oscilloscope. Two different types of graphical displays of voltage, waves, are observed during the course of the experiment. A sine wave and a square wave graphical representation of voltage were observed. A sine wave is fluid when observed and (Lenk, 1997) where as a square wave is not fluid. This was a three part laboratory exercise. Firstly, the dynamic range was determined. Secondly, it was observed and determined that the voltage and specifically the rootmean square voltage is independent of the frequency it is emitted at. Lastly, the time was determined from observing the frequency as represented on the oscilloscope at 2 different frequencies but at two different types of waves, sine wave and square wave. Determining the frequency from the time measurements collected from the oscilloscope was done, and in turn from these calculations it was established that wave functions do not affect the frequency emission value nor the period observed on the oscilloscope. One of the major advantages of using an oscilloscope is its capabilities (Fogiel, 2002)to provide large quantity of information about the signal that is being measured as opposed to other devices. When analyzing a current, one can actually see if the shape of the voltages frequency is the...
