I need to design a digital circuit using TTL chips (adders, registers, etc.) to perform integration on binary values. The binary values are converted from analog signals such as a sine wave, constant, square pulse, and saw tooth. I can achieve the process for constants and positive signals using a circuit that performs summation. The problem I am running into is that I cannot use the summation process for a sine wave. The integration for sine, as you would know, is minus cosine, which ends up being a sine wave that is shifted by 90 degrees. In a sense, the input values versus the output values, after a single integration, are delayed by the time needed for 90 degrees. I am looking for suggestions for a circuit design to achieve this. I am aware that an analog circuit could perform these operations in a simple way, but that is not the task at hand. The digital circuit will reside between a pair of A to D and D to A converters. Thanks in advance for you input :)
