FIR Filter Coefficients
Mechatronics Zone 9/6/2013
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
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
This column wraps up our discussion of encoders with information about resolvers, which provide angular data over 360 degrees.
An Undersampling Wrapup
Mechatronics Zone 11/27/2012
Post a comment
Contributing technical editor Jon Titus wraps up his undersampling columns with sample rates and a plot with extrapolated lines.
Undersampling Changes Bandwidths
Mechatronics Zone 10/19/2012
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
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
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
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
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.
Damn the Error Codes
Mechatronics Zone 9/20/2011
Service manuals often give incomplete error or malfunction information and fail to include information on fixing the problem.
My Mercury Wiring Harness Nightmare
Mechatronics Zone 9/13/2011
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.
Former DARPA official and Google executive Dr. Kaigham Gabriel believes sensor companies think too much like suppliers and need to bring their products closer to the consumer.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Engineers at Festo were inspired by how a caterpillar builds its cocoon when designing its new 3D Cocooner printer.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
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.
