coefficient série de fourier

coefficient série de fourier

‎10-20-2012 04:25 PM

Bonjour,

Existe-t-il une solution sous labview pour obtenir les coefficients an et bn de la série de fourier d'un signal ?

La FFT donne la valeur efficace de chaque harmonique mais j'aimerais obtenir les coefficents an et bn.

Merci pour votre réponse.

Cordialement

You can use the “Spectral measurements” express VI. With this VI you choose whether the coefficients are returned in RMS, peak, power spectrum or power spectral density. Also you can choose between linear and dB. I hope this is helpfull.
