The trend in professional audio systems seems to be that audio signals are move and more moving from balanced analogue interfaces and proprietary digital interfaces to Ethernet networking. There are many good reasons for that, which I am not going through in this post, for more information on reasons for transition look my earlier postings →
I saw an interesting writeup 100GbE To Slash the Cost of Producing Live Television at Slashdot. It tells that today live-produced TV is still largely a circuit-switched system. But technologies such as 100 Gigabit Ethernet and Audio Video Bridging hold the promise of removing a lot of of cable and thousands of connectors from a →
EMC Basics #5: I/O as critical circuits article gives some useful tips on the EMC issues related to inputs and outputs. Digital inputs/outputs — The key concern for digital interfaces is ESD. A secondary concern is radiated emissions. Radiated susceptibility is rare with digital I/O, although possible at very high RF levels. The solutions for →
The growing importance of cloud computing along with the increasing utilization of unified data/storage connectivity and the advent of server virtualization have elevated the popularity of 10Gbps Ethernet.There are several connectivity options are available for 10Gbps Ethernet, both over optical fiber and copper cables. 10GBase-T Technology Revisited article tells that the lack of economical cabling →
It seems that there is a trend to convert video systems over from an old, all-analog system to a modern, IP-based system with cameras powered over the Ethernet line using PoE (Power over Ethernet). Weird AC Voltages in a PoE Camera System post at Control Geek Blog talks about an interesting PoE (Power over Ethernet) →
