igital Electronics/Microcontroller Lab Problem Suppose you have been asked to assist with an experiment. The digital data acquisition system has a sampling frequency of 1, and all analog signals are read in through an 8-bit digital-to-analog converter with a reference voltage of 5V. The voltage signal generated by one of the transducers that you need to collect data from is expected to generate a signal given by () = 1 2 0 1 sin(21) 2 sin(22) where 0 = 5 1 = 2.5 2 = 5 103 1 = 500 2 = 250 The experiment is run several times, and there is clearly a problem. In some cases, the data just shows a constant value of 2.5V for the entire time interval. In other cases, you pick up a waveform with a frequency that matches 1 but the amplitudes differ substantially. In none of the cases do you see any evidence of a harmonic with a frequency that matches 2. 1. Why is the 1 harmonic not being resolved properly? 2. Why is the 2 harmonic not being resolved properly? 3. In a moment of frustration, your lab supervisor instructs you to double the sampling frequency AND amplify the
