Explanation / Answer

PROBLEM 6) An oscilloscope plots a graph of voltage versus time while a spectrum analyzer plots a graph of signal magnitude versus frequency

1) Name three reasons that sinewaves are important

linear systems response to sinusoidal input in a unique way i.e a sinusoidal input always gives sinusoidal output

variety of signals can be created from superimposed sinusoids

It retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property.
