Timeroc weighting

WebName Type Description; method: TEXT: The weighting method to use. The available methods are linear (or its alias trapezoidal, for those familiar with numeric integration methods) and LOCF, which stands for 'last observation carried forward'.linear fills in missing data by interpolating linearly between the start and end points of the gap.LOCF fills in the … WebThe Impulse time weighting is about four times faster than Fast, with a short rising time constant but a slow falling one. It is little used in most countries these days and so can usually be ignored. Fast corresponds to a 125 ms time constant. Slow corresponds to a 1 second time constant. Impulse has a time constant of 35 ms.
