<p>A microprocessor based system to convert the Walsh spectrum of a frequency limited signal to its Fourier spectrum has been designed and built. The entire processing hardware is implemented on a single PLS-401 card, which consists of an Intel 4004 microprocessor, read only memories to store the conversion program and matrices of constants, random access memories to store results, and input/output ports. The converter can process up to 32 coefficients, and utilizes an 8-bit word length. For test purposes, the Walsh spectra are programmed into a read only memory, and the Fourier spectra are displayed in binary form on an LED matrix. The maximum conversion time is 1.81 seconds, and the maximum absolute error is 2.03% of the largest possible coefficient.</p> / Master of Science (MS)
