Question

You have an 8-bit data acquisition card that has an input range of -5V to +5V and a sampling rate of 1 kHz. The card will be used to measure the output of a transducer that has a dynamic full range output of 2 V RMS (i.e. assume output is of the form 2cos(wt). Design an analog conditioning circuit to eliminate problems associated with this dynamic signal measurement. You may use circuit element values from the previous problem above as a basis. Hints Amplification: Decide desired voltage resolution from signal and compare to data card resolution: this decides gain Need to avoid sampling issues: Prevent aliasing.

Explanation / Answer

7 hz
