Question details

3. The picture below shows actual oscilloscope traces taken from the output of a function gen erator. The upper trace shows the signal when the generator is plugged directly into the oscilloscope; the lower trace shows the signal when a tee is attached to the input of the oscilloscope, and a 1502 resistor is hung on the tee, with the other end connected to ground, as shown in the sketch. From this information, determine the Thévenin equivalent circuit of the function generator: Express the Thévenin voltage as Vrh = Vo sin(2πft), and find values for both Vo and f, as well as the Thévenin resistance RTh for the generator. (Timebase set at 400μs/Div, vertical gain set at 5.00V/Div.) Hint: you can treat the oscilloscope as having an (almost) infinte resistance compared to the tee.
