This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

The spectral manipulation of photons is essential for linking components in a quantum network. Large frequency shifts are needed for conversion between optical and telecommunication frequencies, while ...

Bandwidth is the specification that most engineers consider first when they select an oscilloscope. This article provides some guidance on how to select an oscilloscope with the appropriate bandwidth ...
