EEL5225 Principles of MEMS Transducers HW1 Fall 2009 Semester Assigned: Wednesday, 8/26/09 Due: Wednesday, 9/2/09 1) From the specification sheet for the Kulite LEH-1AC-250 series (100 PSI model) miniature flatpack pressure transducer (see attached), determine the following a. Rated voltage input b. Nominal sensor power requirements c. Sensor sensitivity d. MDS and Dynamic Range, assuming a resolution of 0.01 mV for the voltage measurement system (Note the specification sheet lists “Infinitesimal” for resolution) e. Maximum pressure error due to nonlinearity, hysteresis, and repeatability (Note: “BFSL” stands for best fist straight line) f. Maximum pressure error under 10 g perpendicular acceleration (use 10 -6 as worst case) g. Maximum pressure error for a 50°F temperature shift. h. Maximum overpressure

Unformatted text preview: 2) For the speaker static calibration data in the attached Excel spreadsheet, determine the following: a. Actuator authority (displacement per current) b. Full scale output c. Linearity (use all data points to determine analytical expression for LSF line including coefficient of determination, R 2 , and calculate maximum non-linearity) d. Hysteresis 3) For the microphone dynamic calibration data in the attached Excel spreadsheet, determine the following: a. Nominal flat-band sensitivity b. Bandwidth, cut-on, and cut-off frequencies for ± 3dB sensitivity limit c. Bandwidth, cut-on, and cut-off frequencies for ± 10dB sensitivity limit Reminder: Please remember the statement regarding academic honesty in the preparation of your homework solution as detailed in the course syllabus....

### 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.
