Task 4

You have been asked to produce waveforms A and B shown to enable laboratory

experiments to be carried out. Unfortunately, you only have dc supplies and three ac

sinusoidal voltage supplies available. Describe how these supplies can be utilised to produce

an approximation to the waveforms A and B showing formulae and calculations used

(assuming 100V and 50Hz for the fundamental waveform). Using your calculations, construct

the circuit below in Multisim (or something similar) and connect a virtual oscilloscope across

the resistor. You must include a clear screen print of the two circuits along with the simulated

waveforms. Discuss your findings and suggestions for improvements.
