Along with the people living standard unceasing enhancement, the digital control is one of without doubt goals which the people pursues, it the convenience which brings to the person also is cannot be denied, volume control is a typical example, but the people are more and more high to its request, must work, the scientific research for the modern people, the life, provides a better more convenient facility to need to obtain from the digital technology, all to the numerical control, the intellectualized control direction are developing. In the contemporary acoustic equipment, usually uses the potentiometer to carry on the volume control. When frequently carries on the volume control, also is easy to cause the potentiometer to wear appears the breakdown. Therefore, so long as changes the potentiometer adjustment by the machinery adjustment the digital adjustment, may avoid a series of breakdowns appearance which initiates because of the potentiometer attrition. The present paper is precisely in view of the above question, introduced one kind the digital volume control electric circuit which with d/a converter DAC0832, binary reversible counter 74L S193 and 555 timers designs, is controlled the rank to be possible to reach 256 levels, and the periphery electric circuit is extremely simple. Key word: Volume, electric circuit, digital signal, simulated signal

In recent years, China's standard of living of the people of the significant increase in the demand for housing and real estate investment enthusiasm has also risen, making the real estate market is hot, real estate development enterprises have mushroomed in general to grow up fast , Followed by the real estate market, the land of the competition, the competitiveness of bank funds, real estate development enterprises in order to win this competition, it can not be blind to choose projects, the project must be strictly Financial evaluation and analysis of the feasibility of its full and effective verification, is the only way to the fierce competition would not stand in place. In this paper, mainly through the introduction of real estate development projects throughout the pre-planning process, and the project carried out a detailed financial evaluation and analysis, and introduced a number of practical and financial evaluation of a number of closely related issues, such as: risk prevention, financing , Project cost management. Through analysis of the feasibility of the project, and projects to achieve trade-offs. First, the real estate project carried out a number of theoretical knowledge, including the classification of the project, project planning, project location, as well as financial analysis and the concept of the financial statements and their analysis and evaluation methods, and on its financial Evaluation of a mutually supportive relationship with all the preliminary work is closely related to the financial evaluation; Second, the Court of Changchun rich projects, including: project profile, project market demand forecast, the progress of the works projects, measures to ensure the implementation of the project And cost control, project sales and so on; then, the project was carried out financial analysis, including: the cost of the project cost analysis, investment analysis, financial and project evaluation and detailed analysis. Finally, though not involved in a number of financial evaluation, but the success or failure of the financial evaluation is very important. The article used the theory and practice of the method of theoretical discourse, let readers of the real estate development projects at the theoretical level, there is a basic understanding, which also cited an actual case, and the first case An all-round, and then the case for the project cost analysis, investment profits, cash flow analysis, so that readers will be able to make the real estate project financial analysis to a deeper understanding. Through the project evaluation and financial analysis, paper concluded that the current cost of sales as well as change the situation, the project financial evaluation showed that the project is feasible and is in line with the expected yield and the yield industry If other factors in project implementation and to maintain the same level in the forecast, then the project will be completed by the end produce the desired results. This article is the evaluation of the financial analysis, financial evaluation, but things do not exist in isolation, it is the first of a multi-data collection process, it was followed by the collection of data sorting process can last up with a variety of financial statements, and On the basis of these statements to calculate a variety of economic indicators, through analysis of these indicators compared to the final decision of the viability of the project. In fact, the real estate project financial evaluation of real estate development business trade-off is very important, we have every real estate enterprises should pay attention to it, so that both companies to bring profits to the customer can bring the desired product To avoid the follow-up issues, people and social groups to a perfect work.
