A system, peripheral device, and method for authenticating an encryption key before transmitting encrypted messages containing sensitive information are provided. The method includes changing bias voltages applied to bias lines in an input stage included in the channel buffer block using a coupling effect of coupling capacitors during a slewing interval and increasing bias currents in the input stage using input voltages and changed bias voltages. The startability of the dielectric barrier discharge lamp when first being started or after long operational pauses is improved thereby. Also disclosed is a roll of plastic tubing that is sealed transversely at a succession of intervals, with each pair of seals stopping just short of a longitudinal center line of the tubing. 0undecene-7, a benzotriazole salt of 1,8-diazabicyclo5. The present invention is particularly useful in phase locked loops and delay locked loops, in which a controllable oscillator or a controllable delay device is controlled on the basis of the phase difference determined by means of phase detection, in such a way that a control signal can be obtained, the phase lag or frequency of which has a firm relationship to the reference signal.
