A Galena Cat's Whisker Signal Detector - an early radio wave detector used in crystal radio receivers starting around 1905

Devices and methods which detect different kinds of signals such as acoustic signal detection, phase detection and radar direction


  • Optical signal detection - detecting an optical signal
  • Phase detection or phase comparator, a frequency mixer or logic circuit that generates a voltage signal which represents the difference in phase between two signal inputs, used in a phase-locked loop
  • Radar detection - detecting the transmission of radars signals
