Question

Problem #1 (5 points) In Lab 4 you collected a number of measurements with your Arduino and hardware (you effectively created a data acquisition system to analyze the time response of 1st order system). At the following points in the measurement process, describe 1) any/all signal characteristics (analog/discrete/digital, static/dynamic), and 2) any/all information contained within the signal (temperature, voltage, current). a) The room temperature. b) The temperature signal you provided to the thermistor when squeezing it between your fingers and releasing it. What kind of waveform is this (step, ramp, or impulse)? c) The signal output from the thermistor. d) The signal into the ADC on your Arduino from the voltage divider. e) The signal from the Arduino to your computer running Processing.
