What is signal attenuation?
Many use the term “attenuation” without completely understanding it. The term is used in several areas, including medical, audio, and even attenuation terminology associated with brewing beer. Generally speaking, attenuation means “lessening” the thing that’s being attenuated. For example, sunglasses attenuate the sunlight reaching your eyes. Attenuating an electrical signal can mean that the act […]
Design considerations for PoE
by Rich Fry, Director ICT, TDK Corporation of America The adoption of Power over Ethernet (PoE) in various applications is growing significantly, largely due to the added benefit it can provide for both the designer and end users: Fewer cords at workstations lower labor costs, and the ability to run an Ethernet LAN cable that […]
COVID-19 and climate change
A single coronavirus particle mutated and survived the transition from animal carrier to human victim, and so far with verified U.S. cases exceeding one million, there is no known therapy or protective vaccine. An unexpected consequence of mediation efforts is that for the first time in generations, Los Angeles and other urban areas have blue […]
Difference between phase distortion, phase modulation, and frequency modulation
The concepts of signal phase modulation and signal frequency modulation, and the difference between them, are often a source of confusion. Ditto for the related idea of phase distortion. Here, we’ll try to clarify things. To understand phase distortion, recall that any waveform can be considered to be a sum of sine waves of different […]
Microwave Symposium goes virtual, timeframe August
The 2020 IEEE International Microwave Symposium will be a virtual event in August.
When it comes to UV-C LED lights, buyer beware
During the coronavirus pandemic, there’s been a lot of interest in using germicidal lamps to disinfect surfaces rather than hosing everything down with bleach or disinfectant. Lamps are a little easier to work with when you’ve got things like knobs, buttons, and slider controls on test instruments that may not do well when doused with […]
MIM/MOM capacitor extraction boosts analog and RF designs
Metal-insulator-metal and metal-oxide-metal capacitors popular in analog/RF designs because of their desirable characteristics. By extracting parasitics from your models that are important in your design, you’ll get a robust circuit.
Billions of reasons to build a trusted safe and secure IoT world
by Marc Vauclair, Senior Security System Architect, NXP Semiconductors The IoT (Internet of Things) devices we use in our homes, cars, mobile communication devices, and payment systems are also becoming increasingly accessible across healthcare and industrial domains. These billions of connected devices – some forecast 75 billion IoT devices by 2025 — will be a […]
