Question

A signal conditioning system converts a temperature (T) between 20 degree C and 80 degree C into a 2V~ 8V signal (V_T). This signal in turn is fed to an 8 bit ADC with a 5V reference (V_ADC). What is the relationship between temperature T and its voltage output V_T? What is the relationship between the V_T and V_ADC? What is the voltage resolution of V_ADC? What is the corresponding resolution of the measured temperature T? What temperature does a binary output of 10100101 represent? What binary output results from 45 degree C?

Explanation / Answer

1.As we can see that for an input temperature of 20°c ,the output of sensor is 2v and for 80°c,the output is 8v .So we can conclude that Vt=T/10.
