Digital Signal Processing: Frequency Translation without multiplication

Posted: 24 Sep 2007     Print Version  Bookmark and Share

Keywords:DSP algorithms  frequency translation  DSP design  digital signal processing 

Frequency translation is often called for in digital signal processing (DSP) algorithms. There are simple schemes for inducing frequency translation by 1/2 and 1/4 of the signal sequence sample rate. The article takes a look at these mixing schemes, and discusses creative techniques that professionals can use to make their DSP algorithms more efficient.
