AD8132 has its unique internal feedback, which allows you to adjust the output ga

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

The first step: empty cans wash clean. Step two: Unplug the pull ring. Step three: Cut off the bottom of the pot along the red line in the picture, and cut it with scissors. Fourth step: Cut the top of the jar along the red line of the figure, don't cut it all off, leave the part of the white mark in the picture. The fifth step: on the opposite side of the white line from the bottom of the cut open cans, as shown in the red lines.

cover 1528~1610nm range. It is composed of conventional EDFA and extended band Fiber amplifier EBFA (extendedbandfiberamplifer). Similar products have Belllab Uwoa (ultra-widebandopticalamplifier), which has 80nm of available bandwidth to magnify up to 100 channel wavelength channels in a single fiber. It covers the C-band (1530~1656NM) and L-band (1565~1620nm). The British Imperial College (Ukimperialcollege) developed a broadband

Principle and sensing process of Distributed Optical Fiber Temperature Measuring System The Distributed Optical Fiber Temperature measuring system can be divided into three types based on the backward scattering principle: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering Distributed Optical Fiber Temperature Measurem

system Designers have adopted a more manageable zero-bit code, and the hope of commercial optical solitons has been dashed. Because people now start to consider the transfer rate of 40gb/s, RZ has aroused people's interest again. Higher optical signal-to-noise ratios (OSNR) are required at such rates to require higher emission power, and nonlinear distortions such as SPM and Raman stimulated scattering are generated. These distortions can be cleverl

. Optical fiber for amplification In the quartz fiber core layer doped with rare earth elements can be made into amplified optical fiber, such as erbium doped optical fiber (EDF), doped with thulium amplification fiber (TOF) and so on. Amplified optical fiber and traditional quartz fiber has good integration performance, but also has high output, wide bandwidth, low noise and many other advantages. Optical fiber amplifiers (such as EDFA) made of amplified optical fibers are the most widely use
