Product Design: PD5 - Grounding & Shielding - Circuits and Interference (Part 2)
Presenter:
Ralph Morrison
Abstract:
This second session of Grounding and Shielding Circuits takes off where the first session ended. Under discussion will be : the role of digital logic and processors in the audio world; A/D converters; transmission line basics; impedance control and impedance matching; the relation between rise and fall times and frequency spectrum; the need for ground and power planes; decoupling and filtering on logic structures; the interface between analog and digital circuits; digital analog filters; aliasing errors; balanced digital lines and common-mode rejection; multilayer boards; interference problems such as cross talk, ground bounce, via locations.
