DSP Based on High Speed Real Time System for Low SNR Periodic Signal Extracting |
| |
| Abstract: | This paper presents a design and realization for a DSP based on real time low SNR periodic signal extracting system for low SNR signals. It can work at 16.67MHz to extract signals in real time and is proved to be effective and feasible through applying it in vedio signal real time enhancing. |
