Task 3:
PART 1
Your company produces radio transmitters and part of that circuit multiplies a high-frequency sinusoidal carrier signal ππππ, with a much lower frequency audio signal ππππ.
The relevant input and output signals are shown below.
Engineering Maths Assignment
Use one of the graphical packages listed at the beginning of this assignment to plot ππππ, ππππ, ππππππ ππππ, and include a screenshot of your plot as part of your submission. Ensure the scale of both axes is carefully chosen to clearly show the detail of all 3 waveforms.
If you drew a smooth curve linking the peaks of the positive half cycles of the output waveform, Vo, which is called the envelope of the waveform, what can you observe about that curve?
