en
amplitude, <of a signal>
envelope, <of a signal>
modulus A(t) of the analytic signal corresponding to the real signal f(t), written in the form:

f (t) + j g (t) = A (t) ejφ(t)

Note – When a modulated signal is represented by E(t)cos[2πft + θ(τ)] in which f is substantially larger than the highest frequency of any significant spectral component of the modulating signal, the envelope is approximately represented by the curve y = ± E(t).


fr
amplitude , <d'un signal> f
enveloppe, <d'un signal> f
module A(t) d'un signal analytique correspondant au signal réel f(t), mis sous la forme:

f (t) + j g (t) = A (t) ejφ(t)

Note – Pour un modulat représenté par E(t)cos[2πft + θ(τ)] où f est suffisamment grand par rapport à la fréquence la plus élevée des composantes spectrales significatives du signal modulant, l'enveloppe est représentée approximativement par la courbe y = ± E(t).
