11. Change the filter frequency by slowly turning
Multipurpose a knob counter-clockwise.
As you turn it towards the 2.2kHz limit at
this horizontal scale setting, you can see
the change in the waveform. The yellow
foreground waveform now shows the true
signal and has the noise filtered out. With this
setting, the oscilloscope only passes through
frequency content below 2.2 kHz. It filters out
the high freq uency noise.
