Fiber optic transmitters convert electrical signals into optical signals and then inject these optical signals into light-conducting cable. They use light emitting diodes (LED) or laser diodes as ...

Reaching indoor antennas requires more power, offsetting efficiency gains made by today’s solid-state technology ...

pH transmitters, commonly called analyzers, provide electrical outputs that are proportional to potential of hydrogen (pH) inputs. The pH scale is used to express the acidity or alkalinity of a ...
