Voltage Ratio in decibels $(\mathrm{dB})=20\log 10\left({\mathrm{V}}_1/{\mathrm{V}}_2\right)$ b) Express the following ratios in decibels (dB): i) $V_1/V_2=100$ ii) $V_1/V_2=0.1$ c) Change these $\mathrm{dB}$ values to voltage ratios i) $?10\mathrm{dB}$ ii) $3\mathrm{dB}$ d) A Function Generator has a specification that the variation in the output voltage with frequency flat to within $\pm 1\mathrm{dB}$ over the frequency range of $10\mathrm{Hz}$ to $100\mathrm{kHz}$. Find the correspond percentage variation in the output voltage over this frequency range.
