Symbol
fs

en
spurious frequency
frequency of an electromagnetic disturbance causing an unintended response from a given equipment

Note 1 to entry: In the case of a receiver tuned to frequency f0, many spurious frequencies fs can be found from the following formulae:

fréquence parasite, f
fréquence d’une perturbation électromagnétique qui suscite une réponse non désirée d’un équipement donné

Note 1 à l'article: Dans le cas d'un récepteur réglé sur une fréquence f0, les formules suivantes donnent de nombreuses fréquences parasites possibles fs:
