The Importance of Mentors
STEM Connection 11/27/2013
42 comments
Jon Titus, a longtime contributor to Design News, is retiring. In this, his farewell column, he stresses the importance of having mentors, and thanks his own.
Account for Uncertainty
Blog 11/12/2013
5 comments
It is important to keep in mind that measurement uncertainties do not always equal one half of the smallest measurement interval.
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?
FIR Filters Without the Math
Guest Blogs 8/2/2013
2 comments
Previous columns have described how analog and switchedcapacitors filters work and provided a real example of each. Now on to digital filters that process discretetime digital values, rather than analog signals.
SwitchedCapacitor Filter Tests
Mechatronics Zone 7/1/2013
5 comments
Switchedcapacitor filters have a few disadvantages. They exhibit greater sensitivity to noise than their opampbased filter siblings, and they have lowamplitude clocksignal artifacts  clock feedthrough  on their outputs.
SwitchedCapacitor Filters: An Introduction
Guest Blogs 6/11/2013
4 comments
In a switchedcapacitor filter, capacitors and switches take the place of resistors and accurately reproduce the characteristics of continuoustime Bessel, Butterworth, and elliptical filters.
How to Create a LowPass Filter
Blog 5/7/2013
5 comments
Sometimes you will not find a lowpass filter with the specifications you need in an antialias circuit. So you might decide to design your own. But you wonder, “Can I get the same performance I see in application notes?”
An Introduction to Filters
Blog 4/1/2013

This intuitive and empirical approach examines lowpass filters commonly used as antialias front ends for analogtodigital converters.
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.
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
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.
