Why the Capacitor in Your Power Supply Filter is Too Big
https://www.allaboutcircuits.com/technical-articles/why-the-capacitor-in-your-power-supply-filter-is-too-big/
The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used.

Benchtop testing a battery for radiated immunity
https://www.edn.com/benchtop-testing-a-battery-for-radiated-immunity/
You wouldn’t think that batteries could fail radiated immunity testing, but today’s more sophisticated Li-ion battery packs include battery management system (BMS) circuitry that monitors the charge/discharge state of each cell, as well as ensuring the battery is automatically disconnected from the system its powering should it detect a fault

Planning the design cycle for adding an antenna to a wireless device
https://www.edn.com/planning-the-design-cycle-for-adding-an-antenna-to-a-wireless-device/
The design cycle is a little different when the product is wireless and requires an antenna. Antennas change the design process, because it needs to be located with care, in the best position on the PCB, and it’s important to consider its relationship with some of the other components in the design.
Ideally, the designer should arrange the RF elements of the design before considering the other components. In this article, we look at the additional stages that an antenna adds to the design cycle, starting with the selection of the most suitable antenna.

Circuit Impedance Calculations Without Cumbersome Simulations
https://hackaday.com/2021/03/02/circuit-impedance-calculations-without-cumbersome-simulations/
Using circuit simulating software like SPICE can be a powerful tool for modeling the behavior of a circuit in the real world. On the other hand, it’s not always necessary to have all of the features of SPICE available all the time, and these programs tend to be quite expensive as well. To that end, [Wes Hileman] noticed an opportunity for a specific, quick method for performing impedance calculations using python without bulky, expensive software and came up with a program which he calls fastZ.
The software works on any network of passive components (resistors, capacitors, and inductors) and the user can specify parallel and series connections using special operators.
