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.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
