    摘要: An antenna is directed to optimally receive an advanced television signal. First, the strength of the signal is measured as a function of the azimuth angle of the antenna, and second the flatness of the signal is measured as a function of the azimuth angle of the antenna. The antenna is then rotated to maximize the flatness of the signal while maintaining the strength of the signal above a minimum threshold.

    摘要: A multilayer circuit structure characterized by reduced crosstalk includes first and second superposed planar dielectric layers. On the first layer, first and second conductor lines are formed, and on the second layer, third and fourth conductor lines are formed. The first and third conductor lines, and the second and fourth conductor lines, respectively, form at least a portion of corresponding first and second differential transmission line. The first conductor line extends in parallel with the third conductor line but is both vertically spaced and horizontally offset therefrom such that a first plane orthogonal to and extending through the first and second planar layers extends through one, but not both of the first and third conductor lines (i.e., a non-overlapping region). Similarly, a second plane orthogonal to and extending through the first and second planar layers extends through a non-overlapping region of the second and fourth conductor lines.
