What's NewOxford University and New Video06-13-10 My schedule is just going crazy having recently been to Denver, Boston, and Philadelphia and now heading to Oxford University in England to teach next week. I hope this bodes well for the economic recovery. But, in spite of the heavy travel, I have managed to generate a new video for the members section. Titled "Analysis and Effects of Vias in Four Layer PCBs," the effects of vias in four layer PCBs are explored using three experiments to generate startling data, one of the experiments is live video and is a real eye opener. If you use or design four layer PCBs, you must watch this video. You will find it in the membership section under "Video" and then "Troubleshooting and Measurements." Travel and 4 Layer PCBs06-05-10 My travel schedule has been crazy lately, a testimonial to an improved economy. But, in-between trips I have been doing experiments. The latest shows a serious problem that can occur on 4 layer PCBs when a trace transitions from one outside layer to the opposite layer. EMC emissions data, ESD generated EMI data, and inter-plane voltage due to signal currents are all the subject of a video I am working on for the membership section. It should be finished and posted early next week. The data is eye catching! The inter-plane voltage generated by a signal changing layers is shown to be up to 45 dB higher (read that" emissions problem") unless a simple design rule is followed. Don't miss this video next week! Members, be sure to use the "Ask Doug" feature. I will be happy to answer your questions. New Audio: Avoid Becoming a Funny Airport Story05-26-10 If you are like me and have to carry a lot of engineering stuff with you when you travel then you will want to hear my tip on smoothing your travel through security. I finish up with two short funny airport stories. You can enjoy the podcast in the membership section under Audio > General Interest. |

Membership Benefits
This section contains videos added daily that cover a wide range of topics including circuit theory and practical lab techniques. As an added bonus, the free videos are included but in a greater optical resolution to improve the overall image quality. These videos help to engage the viewer by providing the material in conversational form. The viewer can then comprehend and process the information in a similar manner that he or she would in a face-to-face conversation. |
This section has audio content covering a diverse array of topics not necessarily found in the video section and vary from electronic news programs to purely educational material. The recording quality of the Member's Section material is more clear and crisp and will be noticeable in the real-time streaming. The Member's Section audio programs will also generally be longer and richer in content than the free audio programs. |
Do you have a design related question you haven't been able to find the answer to? Or, do you have a question on any content on the Circuit Advisor website? As a Member, you can submit questions directly to Doug. If the topic is of general interest, it may be reposted in Doug's blog in the Member's section of the site for all to learn from. Work-related design problems may be eligible for Doug's consulting work. For these services, please visit the Doug's Services tab. |
