There has been a lot of controversy on many of the Internet forums regarding power capability of receivers when driving multi-channel speaker systems. Some argue that when a receiver is rated at ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

Amplification isn’t a difficult concept. You start with a small RF or microwave signal and make it into a large one. Ideally, you wouldn’t be able to distinguish between the two signals except by ...

A while back, I mentioned 1 that we needed a clean test fixture to measure an operational amplifier's input current in the low femtoampere region. But aside from a neat little integrating capacitor ...

Let’s say that for a project you are working on, you need an op amp (of course, I would like it to be one of one of Touchstone’s op amps), and you want to make sure that the amplifier meets your ...

The Cyrus 40 AMP is everything we want in a modern Cyrus integrated amplifier. It’s well-built, fully equipped, looks smart and sounds excellent Optional 40 PSU power supply is effective but pricey ...

Control theory is a vital and standard part of engineering studies: the effectiveness of negative feedback to keep jet-fighters airborne, ferries afloat and nuclear power plants a-non-exploding has ...
