The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

It has been shown that quantum computation can be performed using only linear optical components, single-photon sources, and detectors that can measure the number of photons in a pulse. The role of ...

Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that require negative pulses for switching. Fig 2. Designers can use ...
