1. An A/D converter will convert voltages over a 0 to 10 V range. How many bits must it be to achieve a 1 mV resolution over the entire range? 2. You have an A/D converter that will convert over a range of 0 to 5 V. You input an analog signal to it that has a range of 1 to 3.5 V. What must be the number of bits of the converter to achieve a resolution of 1% of...
According to a manufacturer’s data, hysteresis occurs on the order of 10-6 volt. The resolution of a 16-bit DAQ board with a full-scale operating range of 20 V is 0.305 millivolts. What is the minimum number of bits that the DAQ board should have in order to see the hysteresis of the load cell?
A 16-bit AID converter has a full-scale range+10 V. What is the resolution of this A/D in volts? If this A/D were used to measure temperature using a sensor having a sensitivity of 0.1 mV /PC, what is the resolution in °C? (5 Points)
Problem 3 (30 pts.) A J-type thermocouple is calibrated against an RTD standard within 20.02°C between 0º and 200°C. The emf is measured with a potentiometer having 0.005 mV resolution and an uncertainty of 0.045 mV over its operating range. The reference junction temperature is provided by an ice bath. The calibration procedure yields the following equation: T(°C) = 0.11 + 19.16V - 0.06V2, where the units of voltage V is mV. This second order curve fit has an error...
A temperature sensor based WSN node provides an output of 10 mV to 210 mV over its operating range. Develop a signal conditioning circuit so that the output becomes 0 V to 3.3 V for the operating range. The circuit should offer very high input impedance.

Consider the circuit diagram below used to monitor the output of
a pressure transducer using a data acquistion card. In this
configuration a change in pressure applied ot the pressure
transducer is converted into a change in voltage (vout) which is
then measured by the DAQ. Pressure is converted to voltage in the
transducer according to the following equation:
Vout = {sensitivity} * Pressure = {0.1 [V]/[psi]} * Pressure
Usisg the pressure/voltage relationship of the transducer and
the DAQ information...
1. We wish to sample a small signal that is on top of a large DC offset using a DAQ (Digital Acquisition System such as your nscope) that has a limited input voltage range of ±5 V. If the signal is modeled as Vin-0.1sin(ot)+10 V where 0.1sin(ot) V is the signal and 10V is the DC offset, design a circuit using two op-amps that first removes the DC offset then amplifies the signal by a factor of 40. 2. Repeat...

Pages 4 > of 5 Problem 3 (25 pts.) A J-type thermocouple is calibrated against an RTD standard to within +0.02°C between 0° and 200°C. The emf is measured with an A/D converter having a resolution of 0.075 mV. The reference junction temperature is provided by an ice bath. The calibration procedure yields the following linear equation: T(°C) = 0.11 + 19.2V ,where the units of voltage Vis mV. This first order curve fit has an error of...
