By definition, electromagnetic compatibility (EMC) describes the ability of a system, a piece of equipment, or some other electrical device that utilises electromagnetic energy, to operate in its intended environment without suffering an unacceptable degradation in its performance, or negatively impacting the ability of another device to perform its intended function. This article provides a […]
Today’s thermal imagers are rugged, easy to use, and much more affordable than even just a few years ago. They have become a realistic solution for everyday electrical maintenance. A qualified technician or electrician points the thermal imager at the equipment in question and scans the immediate area, looking for unexpected hot spots. The imager […]
What makes for a perfect low noise amplifier (LNA) MMIC for your microwave system? The answer could be right under your noise figure. LNAs are a critical component in virtually all radar, wireless communications and instrumentation systems. But while the noise figure (NF) performance is often your primary focus, other microwave system considerations related to […]
The interest and use of robotic process automation (RPA) has rapidly increased to support repetitive, labour-intensive and transactional business processes. For many enterprises, RPA has emerged as a best-fit alternative to making huge IT investments in order to make business processes more efficient. Recent studies have found that the service delivery automation (SDA) software market […]
In today’s fast-paced and hyper-connected world, it is vital that businesses adopt a culture that places collaboration front-and-centre. Your best people are not always in the same city, country or even on the same continent. For this reason, you need to have collaboration technologies in place to enable your teams to quickly identify and extinguish […]
Icasa has launched an enquiry into digital broadcasting. Does this mean that South Africa will soon get digital sound broadcasting, which has been available in the rest of the world for decades? If the migration to digital terrestrial television (DTT) is anything to go by, it may still be decades away! Nevertheless, Icasa has started […]
Is computer-aided design (CAD) still the new kid on the block, or are hand drawn designs still relevant in the modern age? This article discusses the developments in CAD since the early days, and addresses whether there is still room for the pencil-and-paper method of design. CAD has been around since the early 1960s, but those early […]
Even passive components can teach electronic devices: as the interface for all central and distributed communication devices, electronics housings and PCB connections mainly determine the functions of a device – and its flexibility with regard to its use in intelligently networked automation structures of tomorrow. Whether Industry 4.0 or the Industrial Internet Consortium (IIC), together […]
With the proliferation of choices between metal-oxide-semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors (IGBTs), it is becoming increasingly difficult for today’s designer to select the best device for their application. This article presents a few basic guidelines that will help this decision making process. Device evolution: Bipolar transistors, MOSFETs and IGBTs The bipolar transistor […]
Service technicians in the field of electrical engineering receive advanced training based on the latest standards at the Limtec+ Training Centre in Diepenbeek, Belgium. More than 2000 participants attend these training courses each year. The advanced building automation platform in the new training building, which was completed in 2017, reflects the principles of Industry 4.0 […]
