Test transistor with a multimeter (1) will be played to the multimeter beeping file, red pen fixed a pole with a black pen to try the other two poles were a few hundred readings when the red pen is the base pole. Repeatedly try. 　　(2) to be tested out of the base, with a red pen connected to the base (B) multimeter has a reading of the triode for NPN (3) to be tested out of the base, with a black pen connected to the base (B) multimeter has a reading of the triode for the PNP general number of a motherboard is only a few.

Testing transistors with a multimeter

　　
(1) the multimeter to the beeping gear, the red pen to fix a pole with a black pen to test the other two poles were a few hundred readings that the red pen is the base pole. Repeat the test can be.

　　
(2) to be tested out of the base, with the red pen connected to the base (B) multimeter readings, the transistor is NPN

　　
(3) to be tested out of the base, with a black pen to the base (B) multimeter readings, then the triode is PNP general number of a motherboard only a few.

Measurement and Diagnosis of Common Mode Inductors - An Overview of Common Mode Chokes

Filter design assumes that the two parts, common mode and differential mode, are independent of each other. However, the two components are not truly independent because the common mode choke can provide considerable differential mode inductance. This differential mode inductance can be simulated by a discrete differential mode inductor. 　　In order to take advantage of the differential mode inductance, common mode and differential mode should not be done at the same time but in a certain order during the design of the filter. First, the common mode noise should be measured and filtered out. By using a DifferentialModeRejectionNetwork, the differential mode component can be eliminated, thus

Vehicle control electronic product software development process

The software development process for automotive vehicle control electronics is a "V" shaped development process. The "V" shaped development process is divided into five phases, i.e., functional design, prototype simulation, code generation, hardware-in-the-loop simulation-HIL, and calibration. 　　 The main tool used in the functional design stage is MATLAB, and by using Simulink, Stateflow, and other tools provided by MATLAB, we complete the tasks of designing the control scheme, designing the functional modules, designing the control algorithms, etc., and carry out the preliminary simulation work. The main tool used in the prototype simulation stage is dSPACE. using dSPA
