Bizon the champion isn't just a bison. He also is a favorite of the "bizons" team.
At a competition the "bizons" got the following problem: "You are given two distinct words (strings of English letters ),SAndT. You need to
E. Divisors
Bizon the champion isn't just friendly, he also is a rigorous coder.
Let's define functionF(A), WhereAIs a sequence of integers. FunctionF(A) Returns the following sequence: First all divisorsA1 go in the increasing order, then all
I was just thinking of a very violent but okay method, but I introduced a better algorithm in the discussion with TK.

Gray value equals to R/3 + G/3 + B/3
Change the corresponding R, G, and B values to the above results and continue to display and store them in the true color bitmap format.
You can also use a color palette to display and store data.

Long-distance Ethernet Technology
LRE technology uses orthogonal amplitude modulation (QAM ). The QAM amplitude modulation uses the signal amplitude and phase to define each symbol. LRE adopts the most advanced QAM technology, has a variety of
compatible with the DVB-C system planned to adopt in China. This will inevitably result in a waste of device incompatibility in the future.
Therefore, the use of DVB-C QAM modulation, not only improve the network capacity, but also compatible with the future development trend. It is the rational choice of broadband multimedia information system, which is suitable for the expressway of China's national conditions by adopting the
channel is still an option, enterprises should consider deploying the 80 MHz channel. It is important for enterprises to evaluate the available channel spectrum before deployment. This evaluation results will affect the results and data transmission speed that enterprises want their networks to achieve.
· 256 orthogonal amplitude modulation (QAM): 802.11ac uses 256
(which makes 802.11ac very attractive to enterprises ).
Finally, remember that the generation of 802.11ac is costly-and costly. This cost is not only for access points, but also for new PoE switches with higher power 802.3at standards, which are required by the new 802.11ac AP.
Signal path control greatly improves the value of 802.11ac
To make 802.11ac more effective, it is necessary to improve the signal path control capability in the RF spectrum.
Taking the transition from 802.11g to 802.11n
backplane capacity exceeding 1Gbps. CMTS allows cable operators to establish high-density and highly adjustable termination systems for their data-over-cable (DoC) services. The core module of CMTS is cable Access Router, which provides routing connections from the Internet or from the internal backbone data network to the RF (CATV) network. By working in conjunction with the QAM modulator (downlink module), if output can be provided in a 6MHz and MC
what kind of technology to take is unknown.Channel assignment for 80211AAccording to the following formula, you can assign a number to a channel in the 5-ghz band and 5 MHz between channels:Center frequency (MHz) = 5,000+5 x n;n = 0,1,2, ... 199Center frequency (MHz) = 5,000–5* (256-n), n=240,241,.. 255Each 802.11a channel with a bandwidth of 20-mhz occupies four channels. The channel center frequency is as follows3 80211g,80211a application in 2.4G
greater than the speed of traditional Modem or ISDN.
ADSL Modulation Technology
Currently, three ADSL Modulation technologies are widely used internationally: Quadature Amplitude Modulation and Carrierless Amplitude-plase Modulation ), discrete Multitone DMT (Discrete Multitone ).
