VMOs Field effect tube has the advantages of both the electron tube and the advantages of transistors, the power amplifier made with it sound mellow, sweet, dynamic range, frequency response is good, so in recent years in the audio equipment has been widely used. 　　 High-power field-effect tube power amplifier, electric. The road is more complex, the production a

According to the Black Gold AX301 Manual, the digital tube position selected signal is named sel[5:0], wherein SEL[5] corresponds to the leftmost digital tube, and sel[0] corresponds to the right-most digital tube, as a convention, in the following description we call the digital tube 5 and digital

I bought a 7-segment LED digital tube with ten pins, but the pins are not on the upper and lower sides, they are on both sides of the left and right. Best reference answer:Use a digital multimeter for pin-by-pin testing. Generally, the 10 pins are 7 segments and two public segments plus one decimal point.The public end is generally in the middle or at the most side, two rows, one row and one symmetric. You can sort other pins by yourself.Assume t

General use of electronic switches can be selected transistor, but the transistor voltage drop and leakage current is not acceptable to the system. So it is necessary to use the MoS

CRT tube Focusing is divided into three kinds of electrostatic focusing, magnetic f

. This involves a very sad thing: when you control the light position and prepare to control the output of ten digits, A single digit will go out, because ten digits are selected for the selected foot. If you select a single digit at the same time, only the same number as the ten digits will be placed, because the same segment of different numbers share the same pin ! what should I do ?? Some people think that there is a problem with the design of the digital

#include Well, that's the code. The actual circuit may have 74h or something. However, it is only one person who wants to record his doubts about why it is B0 rather than 0b. Assume that the digital tube is a common anode digital tube, and the number "3" should be displayed ". Digital tube principle A B C D E F G DP in alphabetical order Corresponding Level 0 0

Dynamic planning, in fact, is similar to the division of the law, the basic idea is to divide the complex problem into a number of simple sub-problems, and then to solve. The difference is that the sub-problems concerned by the division and treatment do not overlap each other, while the sub-problems of dynamic planning are overlapping. For example, in the fast sort, we divide the data into two parts, the two parts of the recursive idea of the sorting of the whole problem into sub-problem sub-arr

This article mainly elaborates the realization planKey words: Open-falcon, Javaxmail, apache-james to achieve complete alarm function, we need 5 steps: 1. Create Rule 2. Data collection 3. Compare rule data with collected data 4. Generate Alarm Data 5. Push Alarm Data And in the pipeline platform, we have integrated small Michae source monitoring system Open-falcon, corresponding to the above analysis of the steps, we give the program is: 1.

Enhanced-N Channel MOS tube (e.g. si2300) switching conditions An enhanced n-Channel MOS Tube's s (source source) and D (drain drain) conduction conditions depend on the VGS, the voltage dropout between the gate and the source. only if vgs > 2.5V, which is vg (G-pole voltage)- vs (S-pole voltage) > 2.5v,d and S-poles conduction. For example: G extremely 3.3V, s extremely 0.1V, vgs = 3.3-0.1 = 3.2V > 2.5V, so D-pole and S-pole conduction, D-Pole

enhanced P-Channel MOS tube (e.g. SI2333DS) switching conditions when used as a switch, the PMOs tube is controlled by the VGS voltage value to control the continuity between S (source) and D (drain drain). the minimum threshold voltage for the VGS is 0.4v, which means that the source and drain electrodes are on when the S (source) voltage-G (Gate gate) Pole > 0.4V. and VS = Vd, the S-pole voltage is eq
