The program for the course "Computer electronics" is supported for high school students and is available to anyone who wants to know about electric lances.

We are the witnesses of the miraculous progress in the sphere of computer technologies. Rіznі electronic circuits to feel good at us every time. As soon as we have a smart phone at our skin, for the help of which I call friends and know them, they need to see them on the Internet, they are gratefully around the clock. At the mass scale of operations for the execution of operations, it is repeated, all the more often the robots play the role of robots, which are more effective and more accurate than people. On the streets, the lights are tied to one of the traffic flow control systems. In an hour, the electronic circuits become cheap and functional, so that they allow you to have a large number of additional outbuildings.

Be-like electronic pristіy - a whole lot of free light of electric signals. Here the stench will arise and die, here they signal to come, schob, flashing through the numerical electric lancers, conceiving the impossibility of finding the visionary rework, wrapping itself in a miraculous melody, a picture on the screen of the ship or the engine on the space.

Knowing that how to work with electronic circuits, how to correctly connect to them the life and supply of electrical signals, change the signal from the viewers, it is necessary not only for electronic engineers, but for those who use electronic disciplines ...

Navchannya in this course is spiraling into practical access to the selection of real electrical and electronic circuits, experimenting with them. Practical busyness is seen at the laboratory, equipped with special headquarters and computer programs.

At the presentation of the program, the order of the items from the subject is transferred to the master class from the version to the selection of the olympic establishments and the establishment of the preprofessional education at a glance (pre-professional education, technology, program).

Having successfully completed the course, the student can take part in the final of the Olimpadi "Vishcha Proba", the Moscow pre-professional Olympiad of schoolchildren and the successful pre-professional sleep from the NDU VSHE. Krym, a leather student, who will be able to start on a selected course, you can take part in the design and preliminaries and prepare your project at the scientific and practical visits of the "Vishchy pilotage" NDV VSHE).

Contingent of scientists- if schoolchildren are out of 10-11 grades, who start in engineering classes at schools, which may be a participant or a candidate for the project "Engineering class at Moscow schools" to the Moscow City Department of Education

1. Power signals.

1.1. General information about electrical signals. Basic parameters and characteristics

We call ourselves an add-on, which converts the input electrical signals, signals more pressure on the outputs. The price of the re-creation is to look for the energy source of the dzherela living.

Behind the family, you will be able to adapt to both the harmonic signals and the pulse signals.

According to the nature of the change, the signal, which is able to accommodate, has an hour to move on to the side of the steady stream and to the side of the change to the stream. The remainder are used for low frequency, high frequency, wide-bodied, vibrating, and other broadbands.

It is due to the nature of the new option and the characteristic of the development of the pressure, the struma and the strain.

The diagram of the substitution of the driver is shown in Fig. 1.1.

The main characteristics of the driver are as follows:

1) Coefficient of strength for a hard time, when the visit starts as a result of the increase at the entrance of the driver before the increase of the pressure at the entrance

,

, de U in і U out - the amplitude value of the sinusoidal springs.

2) Teamwork, Rivniy vіdnoshennu of the increase in the input stream

,

de I in і I vih - the amplitude value of the sinusoidal strum.

3) Coefficient of strength for toughness

,

de P vih - push-pull, as seen at the input, P in - push-in, as seen at the input signal.

In a number of vypadkіv efficiency, they rotate in logarithmic units - decibels (dB):

,

,

.

Viraz performance in logarithmic units of the ma that perevagu, which, with the knowledge of the out-of-the-box performance, the performance of a large-cascade paddlewalker went algebraically to increase the value of the performance improvement.

4) At the zealous viglyad, the efficiency of the driver is a complex value, so that the frequency of the input signal can be stored

,

de A (?) - a module of complex performance strength; φ (ω) is an argument that characterizes the phase shift of the input and output signals.

Amount of module А (ω) in frequency and input signal є amplitude - frequency response (AFC) pressure, which shows the amount of efficiency of the performance of the response from the frequency of the input signal. The presence of the phase of the output signal from the frequency and φ (ω) is called phase - frequency response.

For the ideal driver, the AFC is a straight line parallel to the abscis axis, tobto. for such a signal, however, signals from a frequency from 0 to ∞ will be accepted. In real people there is a swelling of frequencies, at the boundaries of what the efficiency is stronger, there are more, but it is not permissible for the given technical minds. Allow a decrease in performance at the cutoff frequencies no more
times, which corresponds to 3 dB at the logarithmic scale.

5) Pidsiluvach from the side entrance is characterized by input support

.

6) On the side of the outflow pads, it is possible to represent the spikes in the view of the fallow dzherel, the value of which is proportional to the input load (AU in) and outboard support R vix, but start from the formula

.

7) Nonlinear performance the driver is connected with non-linear parameters in the transistors, which can be entered before the warehouse of the driver. Non-linear production before the appearance of the most harmonious warehouse signals at the output signal. The created type can be assessed for help conference of non-linear activities

,

de U 1 - the amplitude of the fundamental harmonics, U 2, U 3, U 4 - the amplitude of the main harmonics.

Ineligible behavior change the meaning of the message at high amplitudes of the input signals.
