Chapter 202: Teacher Luo, you are deliberately making things difficult for Jiang Fan!
………………
Lin Tao and Li Hao's eyes widened.
Everyone turned to look at Luo Longtao.
Luo Longtao said indifferently: "On the battlefield, in order to prevent us from conveying war information, it is a very normal method for the enemy to use interference waves!"
"As information technicians, they must also have the ability to continue to stay in touch with their comrades and obtain accurate data if they pass through the interference waves released by the enemy!"
"However, given that you are still freshmen, the intensity of the interference wave is not great. As long as you have enough technology to use the controller to adjust the band frequency, it is not difficult to obtain accurate information."
Lin Tao shouted: "However, it is the transmitter who takes the lead in adjusting the band frequency to prevent it from being eavesdropped by the enemy, so that it can be emitted regularly or even irregularly!"
"Jiang Fan and the assistant teacher have no tacit understanding of cooperation, nor have they discussed a secret communication plan. How can Jiang Fan keep up with the information of each band frequency if it is sent directly and constantly switched?"
"Teacher Luo, you are deliberately making things difficult for Jiang Fan!"
Li Hao also followed up and said: "That's right! With such difficulty, not to mention us freshmen, even the sophomore veterans may not be able to complete it!"
All the students also nodded.
"If it's not difficult, what's the point of the assessment?"
Luo Longtao asked rhetorically.
Everyone: "..."
Luo Longtao continued to hum: "I didn't add encrypted numbers or letters to the information transmission, so I'm taking care of him!"
"This method is something you must have in the future!"
After speaking, Luo Longtao didn't bother to explain anymore.
As for Jiang Fan, he didn't pay attention to what everyone and Luo Longtao were saying.
I always wear headphones and listen to the information carefully.
At the same time, his hands were constantly fiddling with the band frequency adjuster and eliminating interference waves on the controller.
After about a minute, everyone heard that the assistant teacher's transmission had been completed. They all took off their headphones and looked at Jiang Fan at the same time.
During the process, no one saw Jiang Fan writing the message, but they didn't feel any anxiety.
This made everyone very doubtful. Was it successfully received or not? !
However, everyone still prefers the latter.
Many students tried it just now and found that they could only hear a small part of a sentence clearly.
After they had just adjusted to the frequency of the assistant teacher, the assistant teacher changed it again.
They couldn't react at all.
"Lao Jiang, how are you?"
Li Hao asked Jiang Fan anxiously.
Although they know that hope is slim, they are also looking forward to it in their hearts.
The other students were also staring at him.
Luo Longtao also smiled in his heart when he saw Jiang Fan's slightly frowning expression.
Having been a teacher for so many years, he naturally knows very well that only a handful of sophomores, let alone freshmen, can complete such a difficult task.
"Okay! It's time for the assessment! Jiang Fan, send the information you heard directly to the satellite computer!"
Luo Longtao said.
"yes!"
Jiang Fan opened his eyes suddenly, then quickly opened the satellite computer and typed on the keyboard quickly.
He typed very fast.
"No? Did you really hear it?"
Everyone was surprised.
I wanted to go over and take a closer look, but at this time, Jiang Fan had already finished writing quickly.
Even Li Hao and Lin Tao didn't rush to read it clearly. Jiang Fan had already finished writing it and posted it.
"The report has been sent to you!"
Jiang Fan shouted.
Luo Longtao choked slightly.
"With such a confident tone, could this kid really hear it?"
At this time, the assistant teacher also came over.
"Teacher Luo, I have sent you the electronic version. It includes the time of switching radio frequency, the transformation method, the rhythm point of transformation, and the content of each band."
Luo Longtao nodded, then looked at the whole class, "Okay, now let's all witness it together."
After a pause, Luo Longtao said to Jiang Fan: "Jiang Fan, given that the difficulty of the assessment tasks is relatively high for you freshmen."
"I'll lower the assessment standard. As long as you can complete half of it, you'll pass!"
After hearing Luo Longtao's words, everyone subconsciously looked at the information they heard and were speechless.
Let alone half, even one tenth, they can't even do it!
Lin Tao and Li Hao were also ready to go back and be drilled by the squadron leader.
"Lao Jiang, it was us who harmed you."
Li Hao apologized to Jiang Fan.
Lin Tao also looked apologetic.
Jiang Fan, on the other hand, was not nervous at all. He just patted their shoulders and told them to relax.
"Why are you so anxious? Haven't the results not been announced yet?"
Jiang Fan smiled.
Two people: "..."
At this time, Luo Longtao had already opened the electronic version of the assistant teacher.
Luo Longtao's computer is connected to the large projection screen in the classroom.
Everyone can see it very clearly.
The information conveyed included battlefield information, coordinates of some locations, and requests for help from the headquarters.
Almost every twenty words, the radio frequency is adapted.
Information includes text, numbers, letters, and symbols.
Every band is recorded very clearly.
"Okay! This is the message from the assistant teacher!"
"Next, let's take a look at classmate Jiang Fan!"
After Luo Longtao took a deep look at Jiang Fan, he also directly opened the electronic file sent by Jiang Fan.
Side by side with the assistant teacher’s electronic file!
Lin Tao and Li Hao both clenched their fists and looked nervously at the big screen.
Everyone watched attentively.
But when Jiang Fan's electronic file was opened for a moment, everyone was stunned!
"How is it possible? The information is exactly the same?"
"Teacher Luo, are you sure you opened it correctly?"
Some people died, but not completely...
