A four-terminal (4T) bridge circuit unconventionally supplied by two current sources connected in parallel to opposite arms, named double current bridge (2J) is presented. It has two different outputs from both diagonals. Their output voltages are described as functions of arm resistances and their increments from the bridge balance in relative units are(More)
The proposal of evaluating the uncertainty type A of the stationary random component of measured signal from its regularly sampled observations (auto-correlated) is presented. In the first step the regularly variable components of the signal are indentified and removed from the raw sample data. Then upgraded formulas for standard uncertainty type A of the(More)
