Kalman or FIR Filter for my IMU?
Ian Beavers 3/30/2016 5 comments
In configuring my Inertial Measurement Unit (IMU) for post-filtering of the data after the sensor, I see options for both a decimation FIR filter and also a Kalman filter. Which one is best for my application?
The Drone Dilemma, Part 6: Drone Racing and Yet Another Acronym-- FPV
Scott Deuty 3/30/2016 3 comments
It’s finally time to have a fun blog on drones. Whereas the first five blogs were more about the restrictions of drones, this blog addresses the fun sport of drone racing. For the most part, we dodge the restrictions. Like anything associated with drones, restrictions are leaking into drone racing
How to use slew-rate control for EMI reduction
Steve Taranovich 3/20/2016 2 comments
Many industrial and automotive applications use the synchronous buck converter power-supply topology; these applications also require low conducted and radiated emissions to ensure that the power supply does not interfere with other equipment sharing the same bus
Not Quite Darwin’s Theory of Evolution
Ken Coffman 3/16/2016 3 comments
It strikes me there is natural evolution happening before our very eyes. What was analog, is becoming digital. For the next step, there are already signs that the digital is becoming software. There’s the well-trodden path: analog becomes digital, digital becomes software.
The Birth and Journey of the Ribbon Microphone
Steve Taranovich 3/13/2016 2 comments
The year was 1924 when Dr. Walter H. Schottky and Erwin Gerlach co-invented the ribbon microphone. The design was made up of a very fine ribbon suspended in a magnetic field that could generate electric signals.
Slideshow: Medical Prostheses Marvels
Steve Taranovich 3/10/2016 Post a comment
Engineering advances in the field of surgical amputation and the art and science/technology of designing artificial limbs have made it possible for persons who have lost a limb to receive a prosthesis that is able to function efficiently while looking like the original.
eGaN Technology Reliability and Physics of Failure Blog #1
Alex Lidow 3/1/2016 Post a comment
In this first installment and the next, we will look at the field experience from the past six years of GaN transistors use in a variety of applications from vehicle headlamps to medical systems to 4G/LTE telecom systems. Diving into the failure of each and every part leads to some valuable lessons learned.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
