threshold frequency

Definitions

Electronics

• The minimum frequency which produces a given effect, result, or response, such as detection, activation, or operation. For example, the lowest frequency of electromagnetic radiation required for electrons to be emitted by a surface as a consequence of the photoelectric effect.
• The minimum or maximum frequency which produces a given effect, result, or response, such as detection, activation, or operation. For example, each of the cutoff frequencies of a filter, amplifier, or waveguide.
