Random Vibration			.
This program accepts an acceleration, velocity, or displacement power spectral density function. Given one of these functions, the program then integrates or differentiates as appropriate to find the other two functions. The program also calculates the overall level of each of the three functions.	psdint.exe	psdint.cpp	psdinteg.pdf
