Greetings, Mister Principal: Analog signals and digital signals

It only takes a genius one second to remember the address of this website: (Vertex Chinese), the fastest updates! No ads!? In the large conference room of the Dawn Treader, at one end of the long circular table, there are several black crystals quietly Lying on the table, these are the data from multiple detector surveys of the large void over the past few days.

Broly Augustine from the Storm Council raised his hand, and one of the crystals slowly floated up and flew into the center of a temporarily arranged magic circle. With the injection of magic power, the magic circle began to glow. , and a projection appears inside the crystal, which is exactly the data it collected.

This data looks like a slightly undulating but generally stable horizontal line, representing the magic concentration around the detector. The detection method is to use a material that is extremely sensitive to magic to make a probe, and the probe is in different locations. It detects the subtle magic power or current generated under the magic concentration. Therefore, the range of this detector has a certain range. If its range is exceeded in a short period of time, the instrument will be easily damaged.

After amplifying it, people did not see the expected short-term peak like the feedback from Lord Alberton's detector. Next, the high-level mages looked at several other data, but It was also found that some images have short-term high peaks, while others do not.

"Is it because these detectors were destroyed when they detected the wave crest?"

Wild Regens touched his chin with sparse beard again. At this time, the data of about sixteen detectors were drawn on the paper, floating in front of people's eyes, and compared one by one.

“Or the resolution of these detectors is different, and some detectors cannot detect the signal that appears in this extremely short time.”

Eagles Field looked at Reiner. He knew that Reiner was recently working on a device called a magic computer. Field also received a sample, in which some signal transmissions were related to the signal collection of the detector. The approach was similar, and he thought Reiner might be able to see something.

"Are there specific performance data for these detectors?"

Reiner looked at the person in charge of the observation post, who immediately nodded and took out the previously organized documents from his storage bag.

It can be seen that these detectors generally have extremely high resolution. However, some detectors use analog signal input, while others use digital signal input.

The mages have improved their communication mechanism several years ago in order to deal with the errors that may occur during the transmission of magic signals. Originally, all information would be recorded into the magic crystal as it is, and then the information would be recorded as it is. Playback, such a process can easily be affected by external magic, resulting in distortion and errors.

As a result, under the promotion of Mr. Braggs, the process of replacing analog signals with digital signals began rapidly.

To put it simply, digital signals collect signals at certain time intervals. At the same time, the collected signals are compared with the reference signal, and converted into discrete signals with fixed values ​​according to certain rules for storage. When playing, the The discrete signal is played directly and the original image can be obtained.

The advantage of digital signals is that they can minimize the possible impact of external magic on the signal transmission process. The disadvantage is that it is impossible to "truthfully" transmit the situation at the time to a certain extent. However, with the development of magic technology in recent years, With the improvement, the accuracy and resolution of digital signals are getting higher and higher, and they are almost indistinguishable from the original analog signals. Because of this, Reiner avoided a lot of trouble in the process of developing the magic computer.

Leiner noticed that although most of these detectors collect digital signals, there are also some models that use analog signals. At first, he thought it was because the sampling interval of the digital signal was compared with the impact time. The reason was that it was too long, but after carefully checking the corresponding model and function image, he found that whether it was an analog signal or a digital signal detector, some detected the wave peak, and some did not.

Your Excellency Alberton's detector naturally uses digital signal transmission. Although its accuracy and resolution are higher than those of the previous detectors, it is not actually outside the scope of digital signals.

"Although it can be explained by simple individual differences in detectors, I still think there may be something hidden behind the pattern of this signal."

Your Excellency Alberton looked at these comparison images and said.

Indeed, before this strange crest was discovered, people simply believed that the magical nature of this large hole was no different from the outside. But after it was discovered, no details could be ignored.

Leiner went through the performance data of these detectors again, this time focusing on the differences between those detectors that showed peaks and those that did not.

At this moment, Reiner suddenly had a burst of inspiration.

This fleeting inspiration quickly turned into his actions. Reiner put down the document and asked aloud.

"Can you show me the same type of machine as these detectors?"

Hearing Reiner's inquiry, the person in charge of the observation post was stunned ~IndoMTL.com~ and didn't know what Reiner was thinking.

But he nodded quickly and took out the drawings from his storage bag.

This design drawing is not a simple floor plan, but an advanced drawing that can be projected as a whole after inputting magic power. The observation outpost has conducted many measurements before, and in order to repair the detector, they naturally received the corresponding design drawings.

Reiner injected a little magic power, and the drawing on the original plane bloomed with a ray of light, and the image of a cylindrical detector was projected on the paper. According to Reiner's idea, this detector can also decompose and enlarge on its own. The structure of any part.

"This is the detector that detected the crest."

The person in charge of the observation post said.

Everyone looked at the detector in front of Reiner, but they couldn't see anything special.

Reiner studied the detector carefully and confirmed the inspiration in his mind just now. He did not rush to a conclusion, but asked the person in charge to take out the drawings of several other detectors and check them one by one.

Soon, Reiner finished checking the design drawings. He put them down and breathed a sigh of relief. At least for now, his guess was consistent with the facts.

"What's wrong, Reiner?"

Field came up and asked. He also checked the design drawings together, but he didn't see any clues.

"I have a guess, Mr. Field."

Reiner said that he inspired two design drawings at the same time, one with an abnormality detected and one with no abnormality detected.

“Although there are many types of detectors we release for large voids, in general, they can be distinguished into two categories by a certain characteristic.”

He pointed to one of them. This cylindrical detector has a light-sensitive magic crystal that can project what it sees.

"That's those who have the ability to shoot and those who don't."
