OVER QUANTIZING, THE NEXT STEP IN DIGITAL SIGNAL PROCESSING

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Simplification of the analog front end of a signal conditioning circuit can be accomplished by over-quantizing
the input signal and using DSP for gain and offset. In this case, a much higher precision
A/D converter is used than required by the desired output accuracy. The excess bits are then used to
allow the DSP math to give an effective gain to the signal. By a similar function, offset of over
100% can be mathematically removed as long as the input signal does not exceed the A/D input
voltage range.
