To view asynchronous noise on a signal

To view asynchronous noise on a signal
The following exercise shows how to use the oscilloscope to view
asynchronous noise on a signal that is not synchronous to the period of the
waveform.
Connect a noisy signal to the oscilloscope and obtain a stable display.
