Chapter 7, Problem 7.43P
The voltage output from a J-type thermocouple referenced to 0 °C is to be used to measure temperatures from 50 to 70 °C. The output voltages vary linearly over this range from 2.585 to 3.649 mV.
- If the thermocouple voltage is input to a 12-bit A/D converter having a ±5-V range, estimate the percent quantization error in the digital value.
- If the analog signal can be first passed through an amplifier circuit, compute the amplifier gain required to reduce the quantization error to 5% or less.
- If the ratio of signal-to-noise level (SNR) in the analog signal is 40 dB, compute the magnitude of the noise after amplification. Discuss the results of 7.40b in light of this.

A thermocouple is connected to a data acquisition system which is used to measure temperature of air
in a duct. For a step-input, the system measures the temperature accurately at steady state. Assume the
dynamics of the sensor(thermocouple) limit the system's speed of response. The sensor has a time
constant of 0.5 sec. In a given situation, the duct's air temperature varies with time as a sinusoid of
frequency 2 rad/s with amplitude of 10°C. In this case, the measured temperature by the system is a
sinusoid as wellI, as a function of time. The amplitude of this (measured) sinusoid, at steady-state, is

You are part of new automobile design team, and are responsible for designing the sensor data collection system. The specification of the data collection system is that is must be capable of receiving data with a resolution down to 0.1% of full scale (1 part in 1000) for any given sensor. For example, suppose the driver pushes the gas pedal, the motion of which is read by an electronic sensor such that the range of motion is defined from 0 (not pressed) to 1 (fully pressed).
