display the screen as an example (whether it's a computer or a TV), the so-called "non-linear" means that if the voltage intensity V of the cathode camera tube is increased by 1 time times, the intensity of the light output on the screen surface will not increase by one fold. Conversely, if the light-emitting element used by the display is an ideal physical model, the ratio of V to I is a constant k in the input signal strength V (

In the circuit analysis, often hear the so-called phase lead lag what, has been trying to understand, the voltage is added to the device at both ends, for the power output and device input is necessarily the same phase, Ah, why will appear ahead and lag of said. Let's start by listing a few very clear concepts: The coil load is called inductive, capacitive load is called capacitive, pure resistance load is called resistance; for example, the motor is

Computer boot After you have encountered screen phenomenon, boot screen is what caused it, this article for you to introduce some causes of the fault and troubleshooting methods, the following to see the specific content. The cause of the failure of the Power-on monitor screen LCD LCD screen screen failure may be the problem of LCD driver circuit, LCD panel power supply Circuit problems, screen contact is bad, the motherboard control circuit problems caused by. Since the LCD screen after the b

Linear Regulator (LDO)When the output voltage is below the input voltage, a linear regulator (LDO) or Buck converter (buck) must be considered from the load supply and the voltage drop ratioLow voltage drop-down linear regulators (LDOs) are suitable for applications where low noise, low current, and low

This article originated from: http://www.znczz.com/thread-123986-1-1.htmlSelection of filter capacitanceAfter the rectifier bridge is pulsating DC, the fluctuation range is very large. After the general use of the size of two capacitorsThe large capacitance is used to stabilize the output and it is well known that the voltage on the capacitor cannot be mutated, so the output is smoothedSmall capacitance is used to filter out high-frequency interferenc

not lose low-frequency information or DC information. The common-mode level at the output end of the differential mode can be adjusted by the input voltage of the VOCM pin, in this way, the input level can be quickly translated when A/D converter of A single power supply is driven. The rapid overload recovery capability of AD8132 ensures its sampling accuracy. AD8132 can also be used as a differential mode signal driver to transmit high-speed signals

The day before yesterday, a netizen asked about the design mode of the adapter mode (Adapter), said not very good understanding. Can insus.net give a simple example to illustrate. The following animation is the result of insus.net: The above demo, two lamps of the same specification, requires the input voltage of 15 volts. LIGHT1 is used directly, while LIGHT2 is using adapter (power adapter). So Light1 can only receive 15 volts of
