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 ...

Here’s a quick way to determine the bandwidth of a signal when all you know is the clock frequency. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of ...

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 ...
