Abstract
An electronic digital system for performing discrete Fourier transforms in real time. Read only memory (ROM) modules are used as look-up tables for providing inputs for multiplier stages corresponding to sequences of sample signals as well as for logic and other input converting elements of the system. Two such systems are coupled together so that their real and imaginary output signal components may be additively and subtractively combined. The entire transform output is available one cycle period after the last sample input.
