Solutions 2024/2025
Transducer - ANSWERSbasic device used to acquire a measurement
Transducer Indicator - ANSWERSsupplies power to the transducer, has provisions for balancing or zeroing
the transducer, setting gain, etc.
Voltmeter - ANSWERSGives early read on the output of the transducer for adjustments
Tape Recorder - ANSWERSprovides a backup of the data sent
Amplifying - ANSWERSincreasing a voltage level to properly fit a data acquisition system
Attenuation - ANSWERSdecreasing a voltage level to properly fit a data acquisition system by scaling
Filtering - ANSWERSprocess used to remove unwanted noise form data streams
Suppression - ANSWERSsubtract voltage form a signal so that it will properly fit a data acquisition system
Linearization - ANSWERSadjusts a nonlinear input to fit a linear model
Isolation - ANSWERSseparating connections from the DAQ board to protect it from large pulses
A/D Conversion - ANSWERSConverts the analog signal to a digital signal that the computer can read,
possibly using a multiplexor
Resolution - ANSWERSdetermined by the amount of bits used to represent a board
