Abstract: A complex coupler for cold cathode fluorescent lamp (CCFL) is used as a lamp lead wire coupling terminal, which includes a main body, a CCFL socket, and a cable socket. The main body is in the shape of an elongated column with a complex structure consisting of an inner conductive body and an outer enclosing insulative layer. The main body has a lamp coupling surface, on which the CCFL socket is formed for receiving an end of a CCFL and a lamp lead wire provided on that end of the CCFL, and a conductor coupling surface, on which the conductor socket is formed for a cable to connect thereto. The lamp lead wire of the CCFL and the cable can be electrically connected to each other via the lamp lead wire coupling terminal.

Abstract: A method and apparatus for reducing intermodulation distortion is disclosed. In one embodiment, the method comprises the steps of accepting a sampled input signal V(t) wherein the input signal V(t) comprises a plurality of peaks; determining n peaks Vp1,Vp2, . . . Vpn of the sampled input signal V(t) exceeding a clip value Vclip at times t1, t2, . . . tn; and modifying the sampled input signal V(t) by weighting the n peaks Vp1,Vp2, . . . ,Vpn exceeding the clip value Vclip of the sampled input signal V(t) by a function b(t) wherein b(t) is either a hard limiting function or b(t)=f(a1, a2, . . . an;t?tp1,t?tp2, . . . t?tpn), wherein a1,a2, . . . an are weight values corresponding to the n peaks Vp1, Vp2, . . . Vpn, and f(t?tp1,t?tp2, . . . t?tpn) is a smooth shaping function. Intermodulation performance is then selectively improved in selected sub-bands by notch filtering prior to application to the non-linearity.
