1、The Prospects of Precision Waveform Generator Function Now the world in impelled the social cross leap -like progress take the electronic information technology as the premise under, the science and technology rapid development changed with each new day has led the various countries productive force
2、s large-scale enhancement.Thus it can be seen the science and technology has become the various countries competition the core, the electronic information technology appears in particular especially importantly, produced various departments electronic information technology in the national to obtain
3、 the widespread application. At present the monolithic integrated circuit seeps each domain which lives to us, which domain is nearly very difficult to find not to have the monolithic integrated circuit trail.Strolls in on the lively modernized metropolis avenue, all may see as necessary on the stre

5、of measuring appliance control, the computer network communication and the data transmission, the industrial automation process real-time control and the data processing, the widespread use each kind of intelligent IC card, the civil luxury car safety system, the videocorder, the camera, the complet
6、ely automatic washer control, as well as program control toy, electronic pet and so on, these cannot leave the monolithic integrated circuit.Say nothing of the automatic control domain robot, the intelligent measuring appliance, the medical instrument, have lived for us have brought conveniently eve
7、rywhere. These “ the high tech” looked is the like this mysticalness, how does it is constitute, what type procedure is it completes this a series of instructions through and what type way? Let us take the money to be more convenient, to avoid the city traffic disturbance and the traffic jam.Actuall
8、y this also is, the monolithic integrated circuit which controls with the monolithic integrated circuit in us lives the tentacle to be possible and, it is so draws close to our life, the monolithic integrated circuit brings for ours life has so many conveniences.The monolithic integrated circuit stu
9、dy, the development and the application will accomplish one batch of computer application and the intellectualized control scientist, engineer.The science and technology is more developed, the intellectualized thing are more, the use monolithic integrated circuit are more.Looked like study the monol
10、ithic integrated circuit is the social development demand. Statistics have indicated, our countrys monolithic integrated circuit year capacity has reached 1 - 300,000,000 pieces, also every year by about 16% speed growth, but is opposite in the world market our countrys percentage of also 1%.Special
11、ly coastal area production products and so on toy factory most use monolithic, and radiates unceasingly inward, this explained the monolithic integrated circuit application only then just started in our country, has the broad prospect.The raise monolithic integrated circuit application talented pers
12、on, specially popularizes the monolithic integrated circuit knowledge in the engineers and technicians to have the vital practical significance. The function generator is one kind can have many kinds of profiles, like triangular wave, saw-tooth wave, rectangular wave (including square-wave), sine wa
13、ve electric circuit.The function generator has the extremely widespread use in the electric circuit experiment and the equipment examination.Through to the function profile generator principle as well as the constitution analysis, may design one to be able to transform the triangular wave, the sine
14、wave, the square-wave function profile generator.In the modern electronic instrumentation, the signal generating device is a kind of extremely important instrument, along with the electronic surveying technology and the computer technology close union, each kind of profile generator arises at the hi
15、storic moment. It may produce by the user definition willfully the complex profile, thus has the broad application prospects for development. When debugs the hardware, needs to join some signals frequently, observes the electric circuit to work whether normally.The hypothesized instrument is the new
16、 technology which emerges in the recent 20 years, it reformed the survey and the automated method gradually, thus achieved and the reduction product the development time, enhances the product quality to reduce the production cost the goal. Moreover causes it simpler realization with the hardware equ
17、ipment close integration to survey and to control the automation, not only may use for to have the sound frequency range sine wave, the square-wave, the triangular wave, the saw-tooth wave as well as by the above basic profile the random profile which is composed according to the proportion, moreove
18、r frequency, scope, running rate scale-up factor adjustable, causes it to have the corresponding change. This profile generator utilization monolithic integrated circuit technology, through the ingenious software design and the simple hardware electric circuit, has the digital sine wave, the square-
19、wave, the wave tilt and so on the peak-to-peak value adjustable signals.The signaling frequency, may through the keyboard entry, and demonstrated.Says, the digital signal with the existing various types profile generator comparison which produces disturbs slightly, the output is stable, the reliability is high, specially operates simply convenient, the man-machine contact surface is friendly, the cost is low, suits extremely in the physical laboratory teaching and the experiment uses.
