AgileIC: Time for a new hardware design process?
How do I reduce time-to-market? Let me count the ways… If you read enough advertising, white papers, application notes, or product descriptions you will quickly lose count of the various components, tools, and services that promise reduced time-to-market. It seems that everyone has a solution to the problem of shrinking design cycles and just when you’ve […]
Amplifier Theory: Design & Troubleshooting, Part 2
By unclejed613, “Well-Known Member” on Electro-Tech-Online. (Editor’s note: In Part 1, the author began exploring the basic building blocks of amplifiers with the goal of helping the reader “… gain enough knowledge to troubleshoot everything from a discrete headphone amplifier to a kilowatt PA system amp without too much difficulty.” No matter how complex amplifier designs may look […]
Amplifier Theory: Design & Troubleshooting, Part 1
By unclejed613, “Well-Known Member” on Electro-Tech-Online. No matter how “digital” things get in modern consumer electronics, when it all comes down to it, after all of the digital magic is done, air must be moved for you to hear the results. An analog voltage and current must be applied to some type of device that displaces air. […]
