There is an obvious, longstanding trend in electrical and computer engineering (ECE) toward energy conservation and ever-longer battery life. This is especially true in applications related to the Internet of Things (IoT), where expectations of 5- and 10-year battery life for sensors are common. It is also true for battery-powered medical devices… (Show moreShow less) If you will pardon the pun, an electrical and computer engineering (ECE) student must be solidly grounded in mathematical analysis to succeed in calculus, differential equations, Laplace transforms, and other areas of high-level mathematics. Fortunately, one of the classic, proven texts in the field, Principles of Mathematical Analysis, is… (Show moreShow less) An electrical and computer engineering (ECE) student studying waveforms, noise, and signal modulation must generate and view a signal. Lab equipment is sometimes in short supply, and if no function generator is available, there may be no signal to view. Fortunately, many Keysight InfiniiVision X-series oscilloscopes can generate a wide variety… (Show moreShow less) The field of electrical and computer engineering (ECE) is very broad; some well-known universities require 134 credits or more for a bachelor’s degree. Even with that many credits, there is no way an undergraduate education can expose an ECE student to everything that may be required in industry. One area that usually gets limited (if any)… (Show moreShow less) A college student recently told me that food at her school’s cafeteria costs about $132 per week, which is a considerable amount of money. The textbook for the introductory circuits class at the same school lists for $187, or roughly ten days of meals. Over the course of an electrical and computer engineering (ECE) major’s undergraduate career,… (Show moreShow less) Opportunities for electrical and computer engineering (ECE) graduates seem to be virtually unlimited, with growth in health and medical devices, Internet of Things, consumer electronics, supercomputing, artificial intelligence, cybersecurity, smart energy, electric vehicles, robotics, cloud computing, augmented and virtual reality, 5G, machine… (Show moreShow less) The most recent blog post discussed the book Make it Stick, the Science of Successful Learning, by Henry L. Roediger III, Mark A. McDaniel, and Peter C. Brown. The authors’ intent is to replace the theory, lore, and intuition that underlies much current learning theory with scientifically tested facts. The problem with current learning theory… (Show moreShow less) A frustrated elementary school teacher recently told me of her exasperation with teaching math. Just a week before the school’s mandated standardized tests, she had repeatedly drilled her students on adding and subtracting fractions, and nearly every student scored well on her chapter test. Yet when the students took the standardized test, the… (Show moreShow less) The first and second blog posts in this series described divisibility rules for 11, 7, and 21. To summarize: Divisor Rule Example 11 Chop, subtract 3476 347 – 6 = 341 34 – 1 = 33 7 or 21 Chop, double, subtract 2954 295 – 8 = 287 28 – 14 = 14 These rules work because adding or subtracting multiples of n does not change… (Show moreShow less) The previous blog post described the “chop, subtract” rule for determining divisibility by 11. You chop the number’s ones digit and subtract it from what remains. If that difference is a multiple of 11 (0, 11, 22, 33, …), so is the original number. If that difference is not a multiple of 11, neither is the original number. For example, 1083 is… (Show moreShow less)
