Abstract
a. Appareil d'accord pour récepteur radiophonique. b. Appareil destiné à une plage d'incertitude de +- DELTA f entourant la fréquence fi recherchée vérifiant si la fréquence de l'émission est égale à fi +- DELTA f, DELTA f étant un échelon de fréquence connu, et dans l'affirmative, l'appareil fait varier sa fréquence d'un échelon de fréquence DELTA f et vérifie par comparaison si la nouvelle fréquence de l'émission est toujours dans l'intervalle fi DELTA f, si oui la nouvelle fréquence est considérée comme la fréquence de réglage et si non la première fréquence avant addition de l'échelon de fréquence DELTA f est considérée comme fréquence de réglage.
