11.5 A temperature sensor is connected to a 16F873A ADC input. The sensor has an output of 40 mV/?C. The ADC operates with a 4.096 V reference. (a) For a certain temperature value, the ADC output reads 1010011100. What is the equivalent temperature for this reading? (b) The measured temperature is to be displayed on a digital display, showing values in the range 00.0?C to 99.9?C. Describe what data manipulation steps can be taken to achieve this, using fixed-point arithmetic only.

11. 2. A 16F873A microcontroller is supplied with 5 V. Its ADC is connected so that the voltage reference is taken from its supply voltage and ground. (a) What is the ADC resolution, and what is the value of the ADC digital output, for each of 1.000 V, 2.000 V and 2.500 V? (b) Repeat (a) for if the voltage reference has been changed to an external one, of value 4.096 V.
Choose proper ADC for a temperature sensor, whose transfer function is: 0.02V/oC. When the temperature changes from 0o to 100oC, with resolution of 0.1oC, a) What should be the reference voltage for the chosen ADC? b) What is the word size of the ADC? c) When the temperature is 99oC, what’s the output of the ADC?

Calibration and sensing Consider a thermistor temperature sensor (Fig. 1) with a pull-up resistor R1 connected to a 10-bit analog-to-digital (ADC) converter (a full scale No-210-1=1023 counts corresponding to the reference voltage Vref). The thermistor is used to measure temperature in the total input span from -10°C to 110°C. knots n(t VO R1 A/D GND Temperature Fig. 1 The output count of the thermistor measurements circuit can be modeled by a nonlinear function of...
1. Why can the DSO only measure node voltages when the Function Generator is the power supply in a circuit (unless it is using a current probe)? 2. Consider Figure 1. According to the calculations in the lab handout, if Z-1kΩ +/6914, then the phase difference (фи-фі) between u(t) and i (t) is 34.6". a. If this v(t) and i(t) were displayed on a DSO (v(t) being a node voltage and using a current probe for i(t) as shown in...
