K ACCELERATION MISSION 390 00001 13 Rev 8 J ul 2004 MISSION PROGRAMMING DATA ACQUISITION TYPES 16 RMS ACCELERATION The RMS Accel acquisition type uses digital signal processing to calculate root mean square acceleration values This algorithm first converts the 2000 sample sec stream of DC acceleration samples to AC values via a continuous digital high pass filter with an approximate 5 Hz cutoff frequency Next each AC sample is squared and then subjected to a leaky integration algorithm which computes RMS Squared The square root is then taken of the RMS squared signal and the resulting data stream is sampled at the user specified sample rate Due to the high degree of computation required for this acquisition type the accelerometer clock rate is reduced to 500 kHz from the normal 1 MHz The Samples Second field requires the entry of a value between 1 and 10 Note that this field displays the rate at which RMS samples are stored not the rate at which RMS values are being calculated nor the rate at which acceleration values are being acquired The mission example shown in figure 9 will compute RMS acceleration values for all three axes at a rate of 4 triaxial samples per second for 15 hours 20 minutes The time reported for each RMS sample in the resulting data file corresponds to the end of each RMS storage interval The Calculated Resolution depends on the full scale range of the accelerometers installed in the G LOGGER wh
