ADSP 21992 noise near 8khz - weird_ed_edison - Jul 27 19:51:00 2004
|
Dear All, Does anyone experience noise around 8khz while using the ADSP21992 DSP? My circuit seems to have some noise around this frequency. I have tried removing all components I believed could be causing it, but it still persists. I was wondering if the 8khz noise is inherent in the DSP chip itself. Thanks in advance for any information. Sincerely, Weird ED |

What kind of noise? audible or electrical? I'd probe around with an oscope first. If it's crosstalk I'd make a small wire loop with the scope probe tip and probe ground . I would then go around the board with this loop to determine the noise source.
