A pH sensor is being used to measure real-time changes in pH of a microbial fuel-cell. An A/D converter with 14 bit resolution and a clock of 3.6 MHz is being used to sample and digitize the voltage readings that lie in a range of 0-10V.1. What is the resolution of the voltage signal? 2. What is the maximum error in Volts? 3. How many bits are needed to achieve a maximum error that is less than 0.2 mV? 4. What is the percent maximum error for V in the range (5 - 10](v)? 5. Find the maximum conversion time if the A/D was a successive approximation register (SAR).6. Suppose that the measurement is corrupted by 3-bit white noise, uniformly distributed. What is the variance of the noise in V and what would be the variance if we perform averaging of N values, where N = 2, 5, 107.
