What does a ASTABLE circuit do? How could these ideas be applied?

The Texas Instruments LM135 Temperature Sensor has a thermal coefficient of 10 mV/°C. You want to use the sensor in a digital data acquisition system to measure a temperature range of -20 °C to +120 °C and need to convert the analogue output to a digital signal. a) In order to achieve a resolution of 0.1 °C and assuming that the reference voltage is 0-10 V, how many bits must the ADC have? b) Using your answer to part (a), what will the actual resolution of the system be? c) A Sample-and-Hold device is required before a signal is passed into an ADC. Explain why a Sample-and- Hold is required and using Figure Q3, describe how it functions. A, Output Input o- CH Mode Control O Figure Q3 S.
