Figure Q2.1 represents the true value of a noisy signal which is to be displayed on an oscilloscope, in order to estimate the amplitude and period of the underlying sawtooth waveform. a. Suggest appropriate vertical axis and timebase settings for the oscilloscope. b. How should the oscilloscope be triggered? Your answer should indicate where on the waveform you plan to trigger (and why!) and how the oscilloscope can be configured to achieve this. c. Two oscilloscopes are available, a 500 MHz 3 GSPS model and a 100 MHz 500 MSPS model. i. Explain what these specifications mean. ii. How will the displayed waveform differ between the two scopes? iii. Which scope is better suited to the measurement described?
