For phonetic signal modulation, if the pass band range of the band pass filter ( bpf ) is 300hz - 3400hz, the anti - noise properties of laser are approximately independent of bias current and parameters of the cavity ; when the pass band range of bpf increases to a certain degree, modulating bias current and parameters of the cavity can improve the anti - noise properties of laser
對語音調制情況,如帶通濾波器的通帶范圍取為300hz - 3400hz ,則激光器的抗噪聲性能基本不依賴于偏置電流和腔內參數;當帶通濾波器的通帶范圍增大到一定程度,調整偏置電流和腔內參數可以實現半導體激光器的高抗噪聲性能。Skj ( jjw ) series of ac purifying regulated power supply, incorporating functions of regulation and auti - inter ference, designed and muters, xerox, video equipments, medical instrmments and other electr onicinstrmmerts and autocontrol systems for is wide vange of regulating, high precicion, quickacting, high effciency, small itcan restrain restrain sharp voltageand protect from moise of electric power net
