FIR Filter Coefficients
Mechatronics Zone 9/6/2013 2 comments Suppose you wanted to create a FIR filter with your own requirements. How would you find the necessary coefficients, and how many of them would you need?
Switched-Capacitor Filter Tests
Mechatronics Zone 7/1/2013 5 comments Switched-capacitor filters have a few disadvantages. They exhibit greater sensitivity to noise than their op-amp-based filter siblings, and they have low-amplitude clock-signal artifacts -- clock feedthrough -- on their outputs.
Even More on Rotary Encoders
Mechatronics Zone 3/5/2013 2 comments This column wraps up our discussion of encoders with information about resolvers, which provide angular data over 360 degrees.
Undersampling Changes Bandwidths
Mechatronics Zone 10/19/2012 9 comments Before you choose a frequency, you should understand how each upper and lower sampling frequency affects aliasing of signals in the 8MHz bandwidth.
Motor Kits Let BLDC Designs Roll
Mechatronics Zone 9/14/2012 4 comments If your design plans include a brushless DC motor, contributing technical editor Jon Titus recommends starting with a motor drive dev kit.
Handbook Can Help Mechatronics Engineers
Mechatronics Zone 9/5/2012 7 comments Contributing technical editor Jon Titus found a free copy of the Electrical Engineering Pocket Handbook, published by the Electrical Apparatus Service Association, particularly useful.
Getting to Know Freescale's Mechatronics Robot
Mechatronics Zone 6/29/2012 13 comments In May, we told you about Freescale Semiconductor's two-legged robot (FSLBOT) and controller board that lets engineers, students, and even hobbyists experiment with the robot's four servos and many sensors. Here's an update.
Engineering, Science & Math in a Water Bottle
Mechatronics Zone 5/25/2012 32 comments Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
My Mercury Wiring Harness Nightmare
Mechatronics Zone 9/13/2011 8 comments When I attempted to replace a power-window motor on my '96 Mercury I uncovered an amazing nest of wires that controls windows, door locks, and mirror positions.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
