David Sang and Graham Jones Solutions for Chapter: Alternating Currents, Exercise 4: Questions

The Y-sensitivity and time-base settings are $5 \mathrm{V}/\mathrm{cm}$ and $10\mathrm{ms}/\mathrm{cm}$. The trace seen on the $\mathrm{CRO}$ screen is the one shown in Figure .

Determine the amplitude, period and frequency of the signal applied to the $\mathrm{Y}$-input of the $\mathrm{CRO}$.

Sketch the CRO trace for a sinusoidal voltage of frequency $100\mathrm{Hz}$ and ampli tude $10 \mathrm{V}$, when the time-base is $10 \mathrm{ms}/\mathrm{cm}$ and the $\mathrm{Y}$-sensitivity is $10\mathrm{V}/\mathrm{cm}$.
