Square Wave

  1. Oct 25, 2004 #1
    I have collected 5000 points of data from a sensor on a rotary arm (which I was trying to control to move with a position time graph that follows the pattern of a square wave)

    My question is, once I've plotted the graph in excel, how can I overlay a perfect (theoretical) square wave to show the discrepencancies in the collected data from the desired setpoint?

    Do you know the position vs. time data for the perfect square wave?

    Enter them into excel, and create a second data series on the same chart.
