A capacitor varies linearly from to as pressure varies from 0 to 100 kPa gauge. Devise a circuit using an LM331 that converts this to a frequency with a maximum of 20 kHz at.

Then determine the appropriate of a counterbased ADC that will provide an 8-bit output of 255 at 20 kHz. What is the frequency at ? Plot the frequency versus pressure. Comment on the linearity.
