My current oscilloscope is a four-channel, high-speed, deep memory instrument which is still good for analog work in spite of its age. Newer analog oscilloscopes often have mixed signal options with eight or more digital channels. Even for an analog engineer, these can be useful as you can often be working with ADCs, DACs or […]

How can you get more than one measurement from a single sensing technology?
Getting more than one sensor measurement from a semiconductor sensor package that is perhaps 50% or more smaller than one commonly used a decade ago is no problem. Two and even all three of the accelerometer, gyroscope and magnetometer (AGM) sensors found in an inertial measurement unit (IMU) commonly found in a smart phone are […]
Is RF wireless or an RF-cable transmission?
What is RF? RF stands for “Radio Frequency” and has become a catch-all term for certain wired communications and a large (spectral) range of wirelessly transmitted waves. It’s easy to find wireless RF modules for microcontroller development kits and other design-ready products, but where does RF cable fit in? What does Ethernet have to do […]

PODCAST Umesh Mishra: GaN and power to the people and planet
The wide bandgap semiconductor Gallium Nitride (GaN) has been out of the lab and into products in some markets for almost a decade. But this is a new and exciting time for GaN as it finds its way into rapidly expanding high-speed, high-power applications like data centers, motor drives, EVs, and more. A significant player in this […]
Prototype-ready? Key considerations when outsourcing
Adapted from 3D Printing Technologies for Prototyping and Production, How to Leverage Additive Manufacturing to Build Better Products Unlike the blueprints, product rendering, and 3D models architects use long before building begins, product development is different. Today’s products are designed to be manufactured in thousands or hundreds of thousands, and both parts and assembled products […]
Stereolithography: 3D prototypes and a shrinking time-to-market
In a time when much of the success and profitability of next-generation products rests on time-to-market (TTM), taking designs from concept to high-resolution, fully functional prototypes has become an increasingly critical component of the new product introduction process. And in the brutally competitive electronics market, the 3D/Additive Manufacturing (AM) process of Stereolithography or SLA is […]
Overmolding: beyond form, fit, and function for prototypes
Easier, faster, cheaper — three keywords associated with meeting aggressive time-to-market demands, particularly in the evolving electronics design world. And a critical component of meeting those demands is producing a prototype that does not involve complicated processes, is rapidly manufactured, and does not cost a fortune for low-volume orders. In other words, “easier, faster, cheaper.” […]
Waveforms in oscilloscopes and elsewhere
Waveforms are patterns of signals that propagate through a medium such as water or air, or in the case of electromagnetic radiation, through empty space with no apparent material medium. (It is still not known how this is possible.) Electrical current, of course, can also propagate as a waveform. We call these patterns “waves” because […]

What is sensor fusion?
Today, advanced sensing applications in smart phones and automobiles frequently use sensor fusion. However, advanced industrial applications such as sophisticated robots also take advantage of this technology. Sensor fusion is actually a subcategory of data fusion and is also called multisensory data fusion or sensor-data fusion. For location sensing in smart phones the data from […]
