Now its time to look at your electronic signal in a different way. The oscilloscope features you havebeen using show you voltage (amplitude) vs time,

Set the variable resistor control to mid-range. In addition to the 5ms/div and 0.5ms/div settings forthe horizontal scale, there is also a variable se

If you get the picture on the right then your microphone input is not properly turned on, go to the“Turning On Your Microphone Input” to turn it on. T

IMPORTANT NOTE: The designs for the microphone input port vary throughout the computerindustry. Hence you may get waveforms different from those shown

And this waveformmight looklike this.Contact Elenco Electronics if you have any questions about this.Limitations of Winscope and its interface:By usin
