Transistors Q 1 and Q 2 in Fig. 1 are a matched pair sharing the same emitter and base potentials and therefore have = and = . This is a simple two-transistor current mirror with i E 3 {\displaystyle \scriptstyle i_{E3}} as its input and i C 1 {\displaystyle \scriptstyle i_{C1}} as its output.
Besides amplifiers, discrete JFET matched pairs are also used in the design of voltage controlled resistors, voltage controlled current sources, current to voltage converters, programmable gain circuits, voltmeters, phasers and a wide range of analog computational circuits like absolute value circuits These blocks often are designed with ...
A paired difference test is designed for situations where there is dependence between pairs of measurements (in which case a test designed for comparing two independent samples would not be appropriate). That applies in a within-subjects study design, i.e., in a study where the same set of subjects undergo both of the conditions being compared.
For two matched samples, it is a paired difference test like the paired Student's t-test (also known as the "t-test for matched pairs" or "t-test for dependent samples"). The Wilcoxon test is a good alternative to the t-test when the normal distribution of the differences between paired individuals cannot be assumed. Instead, it assumes a ...
Precision grades may only be available in matched pairs, where one wire is modified to compensate for deficiencies in the other wire. A special case of thermocouple wire is known as "extension grade", designed to carry the thermoelectric circuit over a longer distance.
Paired samples t-tests typically consist of a sample of matched pairs of similar units, or one group of units that has been tested twice (a "repeated measures" t-test). A typical example of the repeated measures t -test would be where subjects are tested prior to a treatment, say for high blood pressure, and the same subjects are tested again ...
A kinetic closest pair data structure is a kinetic data structure that maintains the closest pair of points, given a set P of n points that are moving continuously with time in a metric space. While many efficient algorithms were known in the static case, they proved hard to kinetize , [ 1 ] so new static algorithms were developed to solve this ...
Matched molecular pairs (MMPs) are widely used in medicinal chemistry to study changes in compound properties which includes biological activity, toxicity, environmental hazards and much more, which are associated with well-defined structural modifications. Single point changes in the molecule pairs are termed a chemical transformation or ...
