ProCAT Transfer FunctionProCAT Transfer Function

Transfer Function is the difference, shown in spectral amplitude, between two input channels

One use is to show the transmission losses or gains through a fixture and at what frequencies

Example Of DP(f) UseExample Of DP(f) UseDP(f) spectrums were measured from two 6DOF DP(f) spectrums were measured from two 6DOF machines produced by the same manufacturer. machines produced by the same manufacturer. Both were running @ 10 gRMS.Both were running @ 10 gRMS.Sensors were located at front-left quadrant locations on Sensors were located at front-left quadrant locations on each table.each table.DP fRMS Indicated that machine #2 produced two times DP fRMS Indicated that machine #2 produced two times as much fatigue as machine #1, overall. as much fatigue as machine #1, overall. This suggests that screen time costs of machine #2 can This suggests that screen time costs of machine #2 can be 1/2 those of machine #1 for the same screen results, be 1/2 those of machine #1 for the same screen results, and also that unless exposure time compensation is and also that unless exposure time compensation is made, some products with critical fmade, some products with critical frr may have different may have different EOL.EOL.
