Title (EN) A DIGITAL FM DEMODULATOR WITH A REDUCED SAMPLING RATE
(FR) DEMODULATEUR NUMERIQUE POUR LA MODULATION DE FREQUENCE (FM) DOTE D'UNE CADENCE D'ECHANTILLONNAGE REDUITE
Abstract: front page image
(EN)A method of recovering a frequency modulated signal wherein the frequency modulated information signal (503) is sampled (508) at a rate less than the Nyquist sampling rate, following which the under sampled signal can be demodulated (509) to extract the original information signal.
(FR)Procédé permettant de récupérer un signal à modulation de fréquence où le signal d'information à modulation de fréquence (503) est échantillonné (508) à une cadence inférieure à celle d'échantillonnage de Nyquist, permettant ainsi de démoduler (509) le signal sous-échantillonné pour en extraire le signal d'information d'origine.
