ZERO_ORDER_DATA_HOLD

Published:2009/7/23 22:19:00 Author:Jessie | From:SeekIC

Samples analog signal and holds sample value for period much longer than sampling aperture, as required in some sampled data systems and analog-to-digital converters. Used to sample inputs to accuracy of 0.1% of full scale, using sampling aperture greater thorn 1.25 microsec. Value of C is equal to sampling aperture divided by resistance in charge and discharge path.-E. Nelson, Zero. Order Data Hold, FEE, 11:7, p 26-27.
