All about electronics and circuit design

Power supply electronics

A power supply unit (PSU) is an electronic circuit that converts device input voltage fed to the device being powered to the voltage or voltages needed internally by the electronics device. In typical computers a power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Depending

Mains power EMI noise filtering

Because of the presence of mains current in mains-powered audio equipment as well as ubiquitous AC electromagnetic fields from nearby appliances and wiring, 50/60 Hz electrical noise can get into audio systems, and is heard as mains hum from their speakers. In addition to mains frequency humming, the mains power can also contain higher frequency

Python 30 years old

Python pioneer assesses the 30-year-old programming language https://venturebeat.com/2021/02/19/python-pioneer-assesses-the-30-year-old-programming-language/ The Python programming language, which has never been more popular, arguably thanks to the rise of data science and AI projects in the enterprise, officially turned 30 years old. There are inherent challenges of enabling a language to grow and evolve without sacrificing backward compatibility. Python is

Pascal is 50 years old

Hard to believe it’s 50 years. Suppose C will be hitting the big 50 soon too. 50 Years of Pascal https://m-cacm.acm.org/magazines/2021/3/250705-50-years-of-pascal/fulltext In the early 1960s, the languages Fortran (John Backus, IBM) for scientific, and Cobol (Jean Sammet, IBM, and DoD) for commercial applications dominated. Programs were written on paper, then punched on cards, and one
