Nm. Oldham et al., EXPLORING THE LOW-FREQUENCY PERFORMANCE OF THERMAL CONVERTERS USING CIRCUIT MODELS AND A DIGITALLY SYNTHESIZED SOURCE, IEEE transactions on instrumentation and measurement, 46(2), 1997, pp. 352-355
Low frequency errors of thermal voltage converters are described and e
stimated using a circuit model that includes easily measured parameter
s. A digitally synthesized source is used to confirm the estimated ac-
dc differences in the 0.01 Hz to 40 Hz range.
