In this above Link RMS noise is calculated from Accelerometer noise density why 1.6 factor is multiplied to BW bandwidth
Hello Sharat,
the factor 1.6 takes into account, that the noise contributions do not stop exactly at the cutoff frequency. Typically, the noise decreases steadily above the cutoff frequency, but still makes a certain contribution to the RMS noise. If the frequency behavior corresponds to a single pole filter, then the noise contributions above the cutoff frequency result in an “equivalent noise bandwidth” of 1.57*BW, if the frequency behavior corresponds to a 2-pole filter, then the equivalent noise bandwidth is 1.2*BW.
