If you know or can estimate a low-noise amplifier’s gain or noise bandwidth, you can measure the other spec using only a handful of resistors and an ac voltmeter (Reference 1). The method in this ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

WHILE experimenting on resistance to the electric current, I have devised an instrument in which fluid is used to conduct the current under examination. This may perhaps be of use to some who are ...
