figure isIn the calculation of differential impedance note is:1, in satisfying the DDR2 clock 85ohm~1394 110Ohm differential impedance while satisfying its single-ended impedance, so I usually choose to meet the differential impedance (many of the current mode to take the voltage) and then consider the single-ended impedance (usually the plate factory is not considered, actually do a lot of boards, the problem is not really big, It seems that the dif

As we all know, in Excel tables, we can calculate various formulas for the input data. The table we inserted in Word 2007 also makes it easy to do some simple calculations on the data in the table and converts the data into the desired format. First, data calculation Take the table shown in Figure 1 as an example, we need to calculate the sum of each person and the average per quarter. Figure 1 Average First position the mouse over the

When Excel establishes a financial report, it is usually necessary to calculate the relevant data, which is where we use the Excel program to facilitate the language. In the calculation of data, you need to establish a formula to achieve, and in the use of the formula, you need to refer to the value of the cell to calculate, then in Excel how to use the

Sometimes we have a royalty formula for each product, and the formula used for this calculation exists in the table in the string format. when we use this formula, it is not like the one we wrote: $ a2 + 3*5; in this way, the result can be calculated simply, and it is a string. therefore, we must convert the string int

competition in the system So what do we have to look at in terms of performance test engineers? In a word, we should pay attention to all the above performance points. Ii. Several key terms of software performance 1. Response Time: The time required to respond to the request Network transfer time: N1+N2+N3+N4 Application Server processing time: A1+A3 Database server processing time: A2 Response Time =n1+n2+n3+n4+a1+a3+a2 2, the calculation

Inductance (micro Heng) = the number of turns and the length of the coil cross-sectional areaInductance calculation formula collected online !!!First BatchCalculation of loaded electric inductance: coil FormulaImpedance (OHM) = 2*3.14159 * F (working frequency) * inductance (MH), set the 360ohm impedance required. Therefore:Inductance (MH) = impedance (OHM) Electrical (2*3.14159) Electrical F (operating fre

PHP implementation of Chinese character verification Code and Formula verification code method, PHP Chinese character Verification Code calculation This paper introduces the method of implementing Chinese character verification Code and arithmetic verification code in PHP. Share to everyone for your reference. The specific analysis is as follows: People know that simple numbers or letter verification code

Excel2000 How to create a calculation formula: The following will be for a company's business situation to create an electronic report, and use the calculation formula to do some statistics, please follow the steps below. Step one, click the Sheet 3 tab in the lower left corner of the screen, and then start writing t

Formula Input Tips:1. Multiply the number with the symbol, you do not have to enter the multiplication sign manually ("*").2. The following help visualize the calculation: a. Use the Math toolbar to enter and use the TAB key appropriately; B. Reasonable use of the space bar.3. When you enter the open root, you can use the shortcut key "\" key, enter the absolute value symbol, the shortcut key can be shift+\

interfaces that can adjust the weights of field/document/query items A variety of programming jacks seem cumbersome and can be used without, so we can simplify the calculation of lucence formula Score (Q,D) = Coord (q,d) · ∑ (TF (T in D) IDF (T) 2) Conclusion TF-IDF algorithm is based on the term, the term is the smallest word breaker, which shows that the word segmentation al

function from Matlab to verify: 1 CoV (mysample) Does the data we calculate be the same?Update: Suddenly discovered today, the original covariance matrix can also be computed, first let the sample matrix center, that is, each dimension minus the mean of the dimension, so that the average value of each dimension is 0, and then directly with the new sample matrix by its transpose, and then divided by (N-1). In fact, this method is also from the previous

General MRP calculation formula: Net demand = gross demand + allocated volume + safety stock-plan in transit-actual in transit-available stockGross demand: the demand for inventory, manufacturing, and procurement is not considered, relative to the net demand. If it is an independent demand, then the gross demand = the main production plan demand/(1-The expected product is not enough ). For related requireme
