Anonymous users2024-02-07The digital walkie-talkie is a digital communication mode that digitizes the voice signal in a specific digital coding mode and a specific baseband modulation form, and uses a weighted digital signal processor to optimize the data-based communication mode.
1.Digital walkie-talkies allow for better use of spectrum resources. Similar to cellular digital technology, digital radios can load more users on a designated channel and improve spectrum utilization, which is a solution to frequency congestion.
2.Improve call quality. Due to the in-system error correction function of digital communication technology, compared with analog walkie-talkies, it can achieve better voice audio quality in a wider range of signal environments, and it will receive less audio noise and sound clearer.
3.Improve and improve voice and data integration, and change the weakness of control signals that decreases with increasing communication distance.

Anonymous users2024-02-06In the domestic market, Hytera, Tuopeng and other Shenzhen manufacturers have made relatively high-end digital machines. Compared with analog machines, digital radios have the following advantages: First, digital technology can make more efficient use of radio spectrum resources.
Second, it provides integrated voice and data services, and the digital communication system has stronger data processing capabilities. Third, digital communication technology can improve voice quality on a larger scale, improve communication quality, and reduce voice distortion and data bit error rate. The digital system has excellent rejection of ambient noise, allowing for clear speech even in very noisy environments.
Fourth, the digital intercom system has the characteristics of high spectral efficiency, clear voice, long battery life, strong communication confidentiality, strong anti-interference ability, long communication distance, etc., and has a variety of functions such as single call, group call, full call, emergency call, remote death and resurrection.

Anonymous users2024-02-05Because of the digital signal transmission mode, the digital intercom has a longer transmission distance, better anti-interference, and more abundant functions. Pure digital intercom but the cost will be much higher than analog, now the most popular is the semi-digital system, that is, the building part is analog, the building outside the network part with digital.

Anonymous users2024-02-04Digital walkie-talkie is a way of digital encoding communication relative to analog communication.
Compared with analog walkie-talkies, digital walkie-talkies occupy fewer spectrum resources and are more power-efficient.
There is also a simple design circuit of the digital walkie-talkie chip, through the software power-saving design, so that the power consumption of the whole machine is extremely low, the standby current can be controlled, and the standby time is longer than similar products.
If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP). >>>More
The development status of foreign 3D animation is in a leading position, and the United States is the birthplace and leader of 3D animation, with representative works such as "Toy Story" and "Frozen". Japanese 3D animation works have captivated global audiences with their unique style and rich emotions, and their representative works include "Neon Genesis Evangelion" and "Spirited Away". In addition, there are many excellent 3D animation production companies in Europe and Asia, such as Aardman Animations in the United Kingdom and Illumination Mac Guff in France. >>>More

It's better to learn animation or Wang's education.
When choosing an educational institution, the first thing to look at is whether its main training business is the major you want to learn, and you want a training institution that specializes in accounting to teach you animation well, that's nonsense. Secondly, it is necessary to look at the teaching cases and student works of this training institution over the years, whether the style is rich or not, whether the strength is professional enough, and whether the learning guarantee model is comprehensive enough. In order to attract students, some small institutions with no strength rely on foolery and false propaganda, which can easily make beginners deceived, so you must remember: >>>More
