ABSTRACT:
A digital signal processing system which samples an analog voltage, converts the sample to a multi digit base four number, performs a computation with this number, using base four arithmetic, and converts the result back to an analog voltage. This system is comprised of a system an analog to digital converter, an arithmetic logic unit, a digital to analog converter, a system controller, and a memory. The analog to digital converter samples the analog signal and converts the samples into base four numbers. The arithmetic logic performs computations on the samples. The digital to analog converter converts the results of the computations back into analog signals. The system controller controls the operation of the arithmetic logic unit, and the memory stores the command instructions for the system controller. The main advantage of using base four arithmetic instead of binary is much faster through put.
