How To Reverse Engineer, Featuring the Rigol DS1054Z article and videos in it show what is inside a four-channel digital scope. With four channels of input, Dave Jones was wondering how the engineers at Rigol managed to stuff two additional front ends into the scope while still meeting the magic price point of $400, it →
USB to serial port adapters are gadgets that we have a love/hate relationship. We love that we can add serial port to a new PC, but we hate that many of those adapters do not feel reliable in use. Counterfeit copies of USB to serial ICs have caused headaches for users and manufacurers. And it →
EDN magazine has a very good article series on audio electronics related to ground loop issues (issue I have written myself in this blog and my ground loop documents). The article series is based on material that has originally appeared in Linear Audio, a book-format audio magazine published half-yearly by Jan Didden. The G word: →
AnandTech has an interesting article for all those who don’t know everything on semiconductors: An Introduction to Semiconductor Physics, Technology, and Industry. The article says that while it’s rather easy to understand what a transistor does and some of the terminology thrown around, going deeper can be tough. A great deal of the information on →
Here is something to think about this weekend: I thought that not very much new winds comes on HiFi field. But now I came by an interesting idea: current driven speakers instead of traditional voltage driven. EDN magazine has a nice two article series on this: Loudspeaker operation: The superiority of current drive over voltage →
