Connect the two signals used in section 2 above to the "Multiplier" module. Make sure that you record the amplitude of each signal.
Observe and record the resultant waveform in both the time and frequency domain, noting all the important characteristics.
Note:You can synchronise the CRO or Picoby connecting the 2 kHz message to the "Ext" input of the PicoScopeand selecting the "External Trigger". This will result in a stable trace on the oscilloscope.
Define the Signals in Time Domain? The time domain is the type of visualization that most people are familiar with. This method shows variations of a signal with time. The most
