The circuit composed of computing amplifiers is varied and confusing. It is the focus of learning analog circuits. When analyzing its working principles, if the core is not grasped, it is often very big. For this reason, I have collected the application of the world's operational amplifier circuit. I hope that you will be engaged in circuit board repair.All the books and courses on analog electronic technology show that when introducing the operationa

, called Neper. When the gain is calculated in terms of voltage rather than power, the Joule law (Joule's law,p=v2/r) is used, and the formula is: Gain =10xlog10 ((V22/R)/(V12/R)) DB =10XLOG10 ((V2/V1) 2) DB =20XLOG10 (V2/V1) DB This formula is correct only if the load impedance is equal (impedance matched). In many modern electronic equipment, because of low output impedance and high input impedance, the load can be ignored without significantly affecting the calculation result

Rotating an element is a more common need, in support CSS3 browser can be used transform easily implemented, here is the introduction: http://www.css88.com/archives/2168, here is the demo/http Www.css88.com/tool/css3Preview/Transform.html, it is no longer introduced.If you rotate an element under IE, you can only rely on the filter.If you are only rotating in 90-degree units, simply use this filter:filter:progid:DXImageTransform.Microsoft.BasicImage(rotation=i)Where I take 0,1,2,3, respectively,

A matrix rotation angle is associated with four data types: M11, M12, m21, and m22. The calculation formula is as follows: ┏ ┓ ┃ Cos (r) sin (r) 0 ┃-sin (r) Cos (r) 0 ┃ DX dy 1 ┃ ┗ ┛ // The r here is not the angle of the radian; The radian calculation method is: r = angle * PI/180. The following two paragraphsProgramThe above formula is compared and tested: // Var M: igpmatrix; begin M: = tgpmatrix. create; M. rotate (90); showmes

I. Analog Circuit 1. What is the content of kilhov's theorem? (Shi LAN Microelectronics) Kilhov's current law is a law of Charge Conservation, that is, the charge flowing into a node in a circuit is equal to the charge flowing out of the same node. Kilhov's law of voltage is a law of conservation of energy, that is, the sum of the circuit voltage in a loop is zero. 2. Flat capacitor formula (C = ε s/4 π kD ). (Unknown) 3. The most basic characteristics, such as the transistor curve. (Unknown) 4.

This greatly improves the sensitivity of GTEM Chamber shielding attenuation Measurement and is a method suitable for measuring high shielding attenuation of four shielded cables.2. Why should we use the GTEM chamber method instead of the absorption clamp method to measure the four shielded cables?In the measurement of shielding attenuation of R

In modern browsers using CSS3 transform style can be easily done, but for domestic IE browser (especially 7,8) also occupies a large share of the case, compatibility still must be considered, so also deliberately recorded under the use of IE rotation filter.There are two types of rotary filters under IE:The first type:CSS StylesFilter:progid:DXImageTransform.Microsoft.BasicImage (Rotation:1)Where the rotation attribute has only four values: 0,1,2,3, respectively, are: 0 degrees, 90 degrees, 180

It can be said that speakers are the most direct computer peripherals in addition to displays, its quality directly affects the effect of multimedia computers.

The input resistor is a performance indicator used to measure the influence of the amplifier on the signal source. The larger the input resistor, the smaller the current obtained from the signal source, and the larger the signal voltage obtained from the amplifier input end, that is, the less the signal source voltage attenuation. Theoretical Basis: US = (RS + Ri) × I. RS indicates the internal resistance o
