frequency discriminator

Definitions

Electronics

  • A circuit or device which makes fine distinctions between frequencies, such as those between two almost identical values.
  • A circuit whose output voltage is proportional to the differences of its input signals from a given frequency. For example, a circuit which converts frequency-modulated signals into amplitude-modulated signals.
  • A circuit or device which only responds to a given frequency, or frequency interval.
