Abstract

This work presents a digital mixer that receives two signals at different frequencies and produces their difference or their sum. Unlike analog circuits that are limited in their ability to separate between close frequencies and require an additional filtering step, we present a digital signal processor-based circuit with excellent frequency separation capabilities. Since software is used to calculate the output function, the obtained output signal is practically unlimited.
