- What value of output resistance would the "ideal" Function Generator have? Explain.
- A Function Generator is adjusted to give a no-load (open-circuit) voltage of 1.0 V. When a 1 KΩ load is placed across the output terminals of the Function Generator the output voltage drops to 0.8 V. Find the output resistance of the Function Generator.

Voltage Ratio in decibels- Express the following ratios in decibels (dB):
- V
_{1}/ V_{2}= 100 - V
_{1}/ V_{2}= 0.1

- V
- Change these dB values to voltage ratios:
- -10 dB
- 3 dB

- Express the following ratios in decibels (dB):
- A Function Generator has a specification that the variation in the output voltage with frequency will remain flat to within ±1 dB over the frequency range of 10 Hz to 100 kHz. Find the corresponding maximum percentage variation in the output voltage over this frequency range.
