Abstract

To analyze the effectiveness of image planes based on clock edge rates in addition to radiated emissions from a printed circuit board, the following is examined. (1) Effects of an image plane on reducing radiated emissions; (2) The effects of distance spacing between a clock trace and an image plane; (3) The effects of microstrips and striplines on radiated emissions; (4) The effect of a gap/slot in an image plane related to radiated emissions. Results of this analysis are from measurements taken on a specially designed printed circuit board in the frequency domain
