Abstract
Algorithms are proposed for the direct implementation of full-adders and multipliers for delta modulated signals. The new adder offers full-addition capability. The new multiplier can have any arbitrary multiplication constant either greater than or less than 1. Error analysis for simple sinusoidal input is performed. Implementations using simple hardware are proposed. Digital filter based on the proposed arithmetic units is designed. Computer simulation results are presented and trade-offs of various parameters in the design are discussed.
