by James Davis, edukatronik.com Power dissipation is a crucial phenomenon in the field of electronics. It refers to the amount of energy that is transformed into heat during the operation of a device or circuit. This process is unavoidable and can be a significant concern, especially in applications where energy efficiency is paramount. That is […]

What’s a PCIe wireless adapter?
PCIe wireless adapters are one of the ways to connect a computer or server to a Wi-Fi network. There are different formats of PCIe wireless adapters, and there are also USB wireless adapters that compete with them based on convenience of operation. This FAQ reviews the operation of PCIe expansion cards, reviews the use of…
What are edge-based and OOK digital isolator architectures?
Edge-based and on-off-keying (OOK) are common communication architectures used in digital isolators. The choice between the two involves tradeoffs, mostly in data rates versus power consumption. Depending on the implementation, there can also be tradeoffs related to noise and transient response and common mode transient immunity (CMTI). This FAQ reviews how edge-based and OOK architecture […]
How does AI use sensors for object recognition? Pt 2
In addition to healthcare, another prominent use of object recognition has emerged as the capability to see further than ever before has increased dramatically. The James Webb Space Telescope’s (JWST’s) ability to see further also results in a considerable increase in astronomical images. Sifting through these images for new information about the beginnings of the […]
What are the five types of quantum computers?
There are several ways to make the quantum bits (qubits) that comprise quantum computers. The classic image of the “chandelier” descending into a cryostat only represents qubits that need to operate near 0 Kelvin (K). They are used by IBM, Google, and others, but those pictures present a very limited view of quantum computing. This […]
What’s a digitally isolated transceiver?
Digitally isolated transceivers are available for industrial applications, electric vehicles, satellites, communications, data processing, and medical systems. They are available for specific protocols like control area network (CAN), RS485, RS422, and RS232, serial peripheral interface (SPI), I2C, low-voltage differential signaling (LVDS), and others. Some support multiple protocols. They can have a single channel or multiple […]
What’s a PCIe root complex?
The root complex in PCI Express (PCIe) is the intermediary between the system’s central processing unit (CPU), memory, and the PCIe switch fabric that includes one or more PCIe or PCI devices. It uses the link training and status state machine (LTSSM) to manage connected PCIe devices. The LTSSM detects, polls, configures, recovers, resets, and […]
How to locate EMI emissions with near-field probes: Part 3
Part 3 of a series on using near-field probes for detecting EMI sources shows you how to set up a spectrum analyzer and how to detect emissions problems. Now that we’ve discussed the theory of measuring near-field emissions (Part 1) and how to use near-field probes (Part 2) to make the measurements let’s discuss how […]
How to locate EMI emissions with near-field probes: Part 2
Now that you know a little theory of near-field measurements, how do you use near-field probes and a spectrum analyzer to help you troubleshoot and mitigate emissions issues? Remember, as mentioned in Part 1, that deciding whether to use an H-field or E-field probe depends on whether you’ll be probing high switching currents — di/dt […]
How to locate EMI emissions with near-field probes: Part 1
Near-field probes let you find the sources of near-field and far-field EMI that ruin your design, and your day. You don’t need to know Maxwell’s Equations to troubleshoot your designs.
