dolby digital analog pass through

Http://www.eetop.cn/blog/html/48/108448-21685.html In fact, the essence is right, that is, the numbers and analog places are both places. It's not that the two of them have a long angle on their heads. It's very strange. You need to understand why you need to separate them. First, let me tell a story.The business building of our company is located on the third floor, the second floor is simulated, and the third floor is

Before learning a number of modes of electricity, A/D conversion of the knowledge, also Baidu a lot of information is difficult to understand. Forget, first self-righteous, and so on after the study of specialized courses and then again. (You must learn to go home in winter vacation.) Well, that's what it's all about. Reading so much information, the sense of A/D conversion is the voltage (or other analog: such as pressure, image, etc.) into the

hopefully are useful for understanding the DMA module:1.DMA transfer data from one address space to another address space, which is implemented by the DMA controller, does not rely on the CPU of a large number of data collection and transmission, saving CPU resources.2.DMA work consists of four processesDMA Request-〉DMA Response-〉DMA transfer-〉DMA endThere are three ways to transfer the 3.DMA(1) Stop the CPU to visit the memory;When the peripheral device has a batch of data to be transmitted, t

passive transformer?The main reasons is to get better pass-band flatness and to isolate the signal from the noisy ADC input.Transformers has a rather "lumpy" frequency response.An amplifier should produce less variability, typically±0.1 DB over the frequency range.If the design calls for wideband gain, an amplifier provides a better match than a transformer to the ADC ' s inputs.Still looking at frequency response, some amplifiers provide DC coupling

Digital signal divided into baseband transmission and band-pass transmission Band-pass transmission is the modulation of baseband signals Why baseband modulation is needed: In practice, most channels (such as wireless channels) have band-pass characteristics and cannot transmit baseband signals directly, because
