Chapter 304 Frequency Hopping Technology

That is to say, it is equivalent to having an "automatic" hand to play, and because the number of punched holes in the paper roll is not limited by the fingers of the human hand, the number and range of sounds on the piano can be used as much as possible, so the automatic piano Still favored by modern composers.

The famous Rachmaninoff, Debussy, Mahler, Gershwin, and R? Strauss have all written music for this instrument and made paper tapes for performance.

The player piano, the most popular in the past two decades, has a record of producing 500,000 units in two years. Of course, only upper-class families can use it.

Now, this automatic piano gave Cyric a great hint.

What tips? Of course it is about the development of electronic communication technology!

Now, all kinds of weapons in Germany are improving. For example, all kinds of missiles are the simplest radio command guidance. This kind of thing is easy to be interfered with!

There are also a large number of radio stations and radars equipped by the German army, which are easily interfered!

How to improve anti-interference ability? In later generations, this is already a consensus!

frequency hopping.

For example, in terms of communications, old-fashioned radio stations are quite backward and have little anti-jamming capability. Advanced armies are equipped with frequency-hopping radios. According to the prior procedures, the frequency is constantly changed so that the other party cannot interfere.

And this technology comes from the automatic piano!

"If we use the principle of this automatic piano to formulate the order of frequency changes in both aspects of the communication terminal, we can greatly improve the anti-interference ability of communication..." Cyric grasped something sharply and muttered to himself said eloquently.

I am not omnipotent, it is impossible to remember everything, and I have actually forgotten about this important invention related to the communication system.

If you use this method to communicate, your own missiles will no longer be subject to electromagnetic interference, and your own communications will not be interfered!

"Frequency hopping communication? This idea is very good, it just solves a big problem in communication." At this moment, a voice echoed next to the ear.

Cyric turned his head and saw an equally excited face.

When Eva was in college, she studied communication! Although she later pursued art and gave up her major, Aiwa is a pretty smart girl, and her math skills are extremely rich!

Now, hearing Cyric's words, Eva was also quite shocked. A new window suddenly opened in front of her, and she had the urge to engage in this frequency-hopping communication technology!

Before the divorce, she often heard a lot of things from her husband. Although her husband was also Jewish, he was very supportive of Hitler. When his husband was talking about torpedo correspondence, he encountered these problems.

Now, she has suddenly found a plan, although it is not at odds with her!

Looking at the woman in front of him, Cyric suddenly asked, "Have you ever acted naked before?"

Cyric's words made Eva blush, and even Hannah on the side was unhappy. She trusted her husband, but such a question would hurt her self-esteem too much.

However, Aiwa could only blushed and nodded in agreement. At that time, she was still too young, and if she was given a chance to choose again, she would definitely not pick up that film.

Now, will he be looked down upon by General Cyric?

"Okay, that's you!" Cyric finally linked her to Heidi in history, and starred naked. There is no one else in this era, it's her!

"Eva, are you interested in contributing to the empire?" Cyric said, "If you follow my request, you will become a Holy Aryan."

The title of Holy Aryan is now a dream of many people. After constant propaganda in Germany, every non-Germanic person hopes to obtain this title.

It takes no effort to get it!

Historically, Heidi - Rama and piano composer George - Antell designed an aircraft navigation system. George conceived of a pair of paper rolls, placed inside the plane and the torpedo, respectively, to specify the sequence of changing frequencies.

By 1941, they had completed this research and applied for a patent for their "frequency hopping" device design. This "frequency hopping technology" was later known as "spread spectrum communication technology".

This is a method of communication to guide torpedoes and is controlled by a player piano-like device that has a unique sequence of 88 possible steps. Torpedoes can be manipulated by sending only a fraction of the entire message on each frequency.

Their research results are quite great, and it can be said that they have opened a door to a higher level of radio communication!

This is only 42 years, and they originally wanted to donate this patent to the US government, hoping to help in World War II.

Sadly, when Heidi opened the drawing, she explained that some parts of it worked like the basic mechanics of a player piano. But military officers at the time thought it was ridiculous.

To them, Heidi herself was more attractive.

Moreover, since Heidi's first marriage was with Mandel, who supported Hitler, CIA personnel wondered whether Heidi was fooling the military with this thing.

As a result, this technology was not used in World War II.

Now, Cyric suddenly met Eva. The current Eva has not changed her name to Heidi. Moreover, she is not disgusted with the current German government. In this case, it is better to appoint Eva to quickly transfer this kind of Practical frequency hopping system!

Only then did Hannah realize that Cyric had something important to do, not joking, and didn't care that Eva had acted naked. Just to prove something.

"I'm very willing to do anything," Eva said excitedly.

"Improve the frequency hopping communication technology we just said." Cyric said: "The Empire will set up a special laboratory to provide you with sufficient funds and personnel, but it also requires you to keep it confidential. The Empire helps a lot."

"Yes, I am willing to serve the empire." Eva agreed immediately.

The influence is subtle. When Germany did not slaughter Jews in large numbers and used holy Aryans to wash their whites, it was easy to win over more people to serve the empire. These people are the most precious wealth!

Hitler nodded: "The Empire will remember your credit. If this task is done well, perhaps, you can continue to develop in your acting career and bring more excellent films to the Empire."

Eva is so beautiful that she could of course make it to the screen and perform some inspiring films to boost the morale of the military.
