When GIGO meets analog
Articles  
2/26/2007   Post a comment
Not too long ago, the "garbage in, garbage out" principle was well understood: output result would only be as good as the input data. This concept faded as processors got more powerful, and software more sophisticated. But now, it's a return to the quality signal chain, as better analog ICs make it easier and less costly to ensure the input signal is properly conditioned and matched to the application, and there's less reliance on software to clean up what may, in fact, not be recoverable once l
