April 8 -- PBR Seminars will launch "Differential Traces and Impedance," a two-hour technical Webinar, on April 27 from 10 a.m. - 12 p.m. PDT (1-3 p.m. EDT). Doug Brooks, a signal integrity expert who regularly speaks at the PCB Design Conferences, is the featured speaker.
According to Brooks, differential circuits and differential signaling are becoming more common on today's PCBs. Differential circuits have several advantages over their single-ended counterparts, including a better signal/noise ratio, more precise signal timing and immunity from external noise sources. Brooks will explain the advantages and disadvantages of differential circuits compared to single-ended circuits, and cover the sometimes confusing issue of common-mode noise as it applies to each type of circuit.

PBR Seminars is a joint venture between UP Media Group and PCB007.
