A sinusoid signal with amplitude of 20 micro volt and frequency of 20 Hz is captured on a data acquisition system. The signal is corrupted with 10 microvolts of 60 Hz noise (power line). The code below shows the power spectrum of the signal as a function of frequency. Note that x axis is labeled normalized frequency (*pi) where w=2*pi*f/fs. Place a cursor on each peak and indicate the magnitude and verify that the frequency is correct.A data acquisition system works with 16 bits. The signal to be acquired has a dynamic range of 20 mV. What is the A/D resolution of the DA
