Definition of coherer in English:
An early form of radio detector consisting of a glass tube loosely filled with metal filings whose bulk electrical resistance decreased in the presence of radio waves.
- The coherer, however, had several defects in that it was not very sensitive and was difficult to adjust.
- The tapper then ceases to function and the coherer is ready for the next wireless signal.
- The coherer was very finicky and unreliable in operation, so there was a vigorous search for an alternative.
