5 A word from some of our past students... I wanted to thank you and your company for the EMI/EMC/Product Safety seminar in San Diego. I honestly was not expecting to learn so much during the four days when so many of these types of company-sponsored seminars are little more than a sales pitch with some info thrown in for good measure. On the contrast, the Compatible Electronics seminar was chock full of information, good design techniques, lessons in how not to do things, and how to apply the current and forth-coming standards. Upon my return to work I immediately found problems with a PC board we are having made for us - a ground plane directly under a common mode choke. These types of things used to not concern me, but now I understand why you shouldn t do that. Thanks again for a job well done! Best regards, -Robert- Robert Morgan Sr. Hardware Engineer Cubic This 4-day seminar was very well outlined. The knowledge and experience of the course instructors along with their practical examples were a valuable part of the lecture. The written course material will also be a valuable reference. Best Regards, Kevin (SIEMENS) I have attended many seminars over the past years and I must say this one with Compatible Electronics has been the best. I must say that Jeff and Shirish were both outstanding. Both of them gave answers to real world problems. If someone asked a question, both Jeff and Shirish would take the time to think about their answer and equate the answer to a real world problem that each of them has had to deal with in solving problems. In the most part I would recommend this seminar to my colleagues. I am using examples from the seminar to enhance the design of our product. Regards Tom Grotkin Pulmonetic Systems Inc

7 This seminar is intended for design engineers and technical project managers involved in FCC and international compliance of digital equipment, Information Technology equipment, and radio frequency devices. Design fundamentals related to EMC, and digital circuit design, will be explained thoroughly. Digital design engineers & project managers EMI test engineers & technicians PWB layout persons Marketing managers Who should attend? Those who think EMC compliance is difficult A brief test to help determine if this course is useful for you. 1. A 115V, 60 Hz power cable cannot radiate 30 MHz noise. True 2. Metallic enclosures will always lower radiated emissions. or 3. Powerline filters can t increase the noise emissions. False? 4. Five 0.02 uf capacitors are equivalent to one 0.1 uf capacitor for a power bus bypass. 5. Signal ground should be totally isolated from the chassis ground to prevent chassis noise from getting onto the signal. All of the statements are false ; if you answered true to any of the above, you should consider attending the seminar.
