Abstract
A data acquisition system which utilizes a fixed frequency anti-aliasing filter and an analog-to-digital converter which operates at a fixed sample rate and a Fourier transform generator and a transform truncator and an inverse transform generator so as to provide sample data output at rates lower than the analog-to-digital converter sampling rate. By using multiple transform truncators and multiple inverse transform generators which simultaneously operate, multiple sample data outputs can be obtained which are free of aliasing phenomena.
