What happens? Why many people have no idea what USB input module means, although they do hear more and more often these words today, isn't it?
Considering the name, USB, people are lead towards thinking this procedure deals with digital signals. Absolutely, usb digital input module is a method of improving the quality of the analog signals, only. Indeed, the naming used usb is rather improper, because it relates to all types of digital processing. But be aware that this modules, and the techniques used deal only with processing signals that are analog in nature. In the USB input module, we can only
- translate them to other digital formats.
Now, what else can we do to our usb file? Well, there are many input module format, and we might need to change our digital audio file from one format to another.
Be aware that the simplest usb file holds data as series of bits. Absolutely this input module type may have data grouped in small packages, in series of bytes, integers, or doubles. Also it allows for another level of information compressing certainly, so in order to change from one file format to the other we need appropriate hardware, firmware, or software data read/write drivers.
Let's take each of these one step at a time, and using few practical examples. Yes, let's cite an example, suppose we have an old record and we want to copy its analog signal on a digital CD, to better protect that recording--CDs are a lot more reliable to hold information unaltered, over time. This means we need to convert the analog signal to digital format, and the best way of doing it is by using usb techniques. First, we need an analog-to-digital hardware module to convert the analog signal into digital format,then we select a specific scanning frequency, to accomplish this task.
