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

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.
For decades there have been rumors that Microsoft essentially copied DRI's CP/M operating system and sold it to IBM as MS-DOS. In just a few days, all will be revealed.
A San Francisco startup called Otto came out of stealth mode recently and released a dramatic video demonstrating its successful test of a technology for self-driving trucks.
Researchers have found a way to use graphene to cheaply and easily turn dirty water into drinking water.
A new 1-GHz vector signal transceiver promises to offer expanded test capabilities for engineers involved in applications ranging from automotive and aerospace to semiconductors and defense.
Researchers at the Masdar Institute of Science and Technology have devised a new method for designing strong, light cellular structures of re-architected metals and plastics with optimized properties.
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.
