The structure of the voter What is the structure of the voter

1. Not gate, also known as non-circuit, inverse phase, inversion, logic negative circuit, or non-gate for short, is the basic unit of the logic circuit.

2. The four-variable majority voter is an important logic circuit used to realize the majority vote function in the circuit. Most voting instruments are often used in the fields of system fault tolerance, decision-making and error correction, and play an important role in various engineering and scientific applications.

3. The voter can be connected in series or in parallel or mixed in series and in parallel. The construction is more flexible.

4. Analysis: The three-person majority voter could have been solved with three two inputs and non-gates and one three inputs and non-gates, but the question limited two inputs and non-gates, so the two problems are actually solved. The first is to limit the use of two inputs and non-gates, and the second is to realize the function of majority voting.

5. There are two kinds of logic circuits of the three-person voting machine. One is that all three people must agree to pass, and the second type is that one of the three people can pass with the consent of one person. Take the first type as an example, the drawing steps of the logic circuit are as follows: in a plane, draw three single-open single-system control switches, and draw a Electrical appliances.

6. Use and non and non to realize the three-person voting machine? First, transform the formula of the logical function and transform the logical expression of the three-person voter.

System function of the voter

1. "poor", "very poor", using the question bank function, first enter the evaluation content, and you can evaluate someone's multiple performances separately. The wireless handheld voting machine has corresponding "excellent", "good", "Adiocre", "poor", "very poor", buttons.

2. This classroom voting machine is an interactive teaching tool purchased by the school, which has the functions of selection, judgment, sorting, teaching evaluation, grouping, and answering. First, it is used to answer questions. After the teacher comes up with the question, the students can use it on the spot to do it in just a few seconds, and the teacher can know the correct rate of the whole class's choice. Second, it can be used for name pointing.

3. The system is connected hand in hand, and there are two straps on the back of each device.The locked DB9PIN socket can connect the system quickly and firmly using the connection cable that comes with the device. The voter can be connected in series or in parallel or mixed in series and in parallel. The construction is more flexible.

What is electronic voting?

Live voting means that the live audience through mobile phonesScan the code to vote on the supported projects, people and programs, and the voting results can be displayed on the big screen in real time. There is no need for manual statistics, and the number of votes is counted in real time and displayed on the big screen.

Electronic voting refers to the owner's decision-making electronic voting system (hereinafter referred to as the "voting system") provided by the municipal housing construction administrative department. Through WeChat and other Internet technologies, voting on matters that should be decided by the owners' meeting or jointly decided by the owners in property management activities according to law. The activities of.

There are two types of electronic voting; wired voting and wireless voting. Wired voting is suitable for fixed venues; wireless voting does not need to pull the line.

Paper voting, electronic voting, online voting. Paper voting: This is the most common way. Voters go to the polling station, collect the ballot and fill in the relevant information, and then put the ballot into the ballot box or give it to the staff.Electronic voting: In some countries and regions, voters can vote through electronic devices.

Counting beans means that because many people are illiterate, they can't use their ballots, and they can't achieve anonymity by raising their hands. So let the candidates sit in a row and put an empty bowl behind everyone. The beans are distributed to voters, and some voters put them into the bowl behind the candidate they like. There are three buttons of different colors on the electronic voting machine.

So as to reduce mistakes and fraud. In general, the start of Internet voting at the shareholders' meeting is a major progress, which can provide enhanced transparency, accuracy and simplicity for listed companies around the world. Electronic voting has become a trend and will become one of the main ways of voting in the future.

How is the voting system of the meeting classified?

1. Audio graphic conference system: The audio graphic conference system mainly uses voice for multi-party communication, supplemented by fax machines and other communication devices to transmit graphic files. This is an early form of conference system.

2. Classification according to the geographical area of the venue: divided into local conference system and remote conference system. The local conference system is a system in the same local conference room, while the remote conference system is composed of off-site remote transmission channels (wired or wireless), transmission equipment and other basic parts.

3. Representatives of the voting system can vote in their seats. There are two types: wireless voting and limited voting. At present, wireless voting is commonly used in the market. The camera tracking system takes real-time close-ups of conference speakers and venue scenes, and the shooting content can be transmitted to the operation room in real time for the operator to monitor and record.

4. Pure video conferencing: If it is a remote meeting, you can choose a pure video conference, so that everyone can meet remotely immediately when entering the conference system, which is very direct and simple.

5. A simple conference system should at least include an amplification system. The purpose of amplification is that everyone who comes to the meeting can hear the speaker of the meeting. Of course, if your company is loud, then you don't need it.

6. Web link voting controller voting controller or extended control equipment is the core part of the speech and voting system. It is controlled and managed by advanced microcomputers to complete the speech and adjust the corresponding parameters to provide safe DC power supply, conference and voting management, and signal amplification for the equipment. And signal output.
