Q: You had convinced me to wait for the new RX-A3060 until I discovered that it does not have 7.1 analog inputs for my Oppo BDP-105. Though I can connect its L/R ...

This application note provides several filter topologies that address the concerns. The following analog input buffers have been divided into four categories: fully differential, single-ended to ...

In the last two blogs, we looked at calculating the noise contribution from the driving amplifier to the total ADC noise in terms of the overall SNR (signal to noise ratio). I stepped through the ...

Hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines. In addition, the common high-density DB-15 ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

The new Razer Huntsman features a mind-boggling set of tweaks — but how well do they actually work?
