Label: style blog HTTP color ar OS SP file on The boss gave two audios, and I felt that they were always there, both occupying the lab place and not making a sound. Lie there to make people feel pity. So I took the time to build a set of Power Amplifier boards to make them sound. Haha, after debugging, it was successful and the effect was good. TI's dedicated audio processing chip is used in the previous stage. For the audio processing capabilitie

Recently contacted the VTune amplifier to do performance optimization. For the average person, often do not want to read so many words to see those instructions. And most want to see is an example, I read the example of amplifier, finally did not find what I want. Very simply, what I want is the performance of the custom time. And after watching the example, I have the impression that from the beginning o

Let's look at the auxiliary theorem: Here, GM refers to the Cross-Guide between the output and the ground transient; rout indicates the output resistance when the input voltage is zero. This is the original statement in the book, but when calculating the formula, we found that the definitions of these two quantities are not completely complete. Is: First, GM is equivalent to cross-export. Remember that it is defined: That is to say, when calculating the equivalent cross-guide, we can intuitive
