The White Noise Generator programed on the Raspberry Pi
POSTER
Abstract
A Raspberry Pi computer, running a Linux based operating system, was programmed for use as a white noise generator. The program was written to output sine waves at a specific frequency with a randomly generated phase. This function generator was programmed specifically for an ongoing undergraduate research project. This research project involves the calculation of the speed of flow through a cylindrical pipe with 128 transducers equally spaced by 0.4 inches down the length of the pipe. The inputted white noise generated serves as an effective technique to induce multiple sine waves of a given frequency to the pipe, as the sine waves are generated at a random phase.
