Two new ICs are described as fully integrated devices that offer direct capacitance-to-digital and impedance-to-digital conversion. The single-chip AD7745 integrates all stages of ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

The presentation of loudspeaker measurements varies wildly from manufacturer to manufacturer. This means that, without independent analysis, consumers are left comparing specifications that were ...
