Matches in DBpedia 2014 for { ?s ?p A plate detector (or anode-bend detector) is a vacuum tube detector circuit used in A.M. radios, although the term is sometimes extended to transistor circuits that similarly rely upon distorted amplification to enhance one half of the received signal over the other. This circuit employs a tube with an indirectly heated cathode, typically a medium-mu triode, or a tetrode or pentode with a sharp cut-off control grid. Partial rectification of R.F. signals occurs in the plate of the detector tube if it is forced into its non-linear region at roughly the zero crossing point of the input signal. This differs from a grid-leak detector, which achieves rectification in the control grid. It also differs from the diode detector circuit commonly used to provide both R.F. rectification and automatic volume control (A.V.C.) bias to the R.F. amplifier tubes.. }
