Unformatted text preview: rate of 14 kHz; c) take a rate of 62 kHz; d) if x(t)=sin(26000 t+ /6) is sampled at a sampling rate of 8 kHz, what reconstruction rate would ensure that the frequency of the reconstructed signal matches the frequency of the original signal before its sampling? 5. Rework the problem for maximum difference output voltage under full load = 14mV and calibration accurate to 0.004 N. Draw schematics. Indicate the composition of the signal at the output of the strain gauge in terms of common mode, normal mode, and parasitic (noise) signal voltages, indicate analytically how instrumentation amp extracts normal mode signal....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
