3. An analog voltage signal is given by V\mleft(t\mright)=3+\cos \mleft(2\pi t\mright?+4\cos \mleft(3\pi t\mright?+2\cos \mleft(6\pi t\mright? 3-1) What is the fundamental frequency in Hz? What is the average value and the

RMS value of the signal? 3-2)Draw the frequency spectrum (amplitude vs. frequency) of the analog signal, with the frequency in Hz. 3-3) Suppose the given analog signal is recorded in a digital form through a digital data acquisition system. The system samples the signal discretely at sampling frequency of 10 HZ. Is the sample frequency appropriate lo avoid aliasing issue? Explain why the selected sampling frequency will (or will not) result in aliasing problem.
