How is writing a testbench and simulating it with modelsim different from simulating it with system verilog? Which is more convenient to use? I see that some companies use system verilog, but some exp...
[size=6]Since my graduation project is to make a digital frequency meter based on AT89C52 single-chip microcomputer, I am uploading the hardware data. Since I am not very good at C language and time i...
The circuit of the protector is shown in Figure 1. The 220V AC power supply is stepped down by capacitor C1, VD1 is half-wave rectified, and VDW is stabilized before supplying to the time base circuit...
I bought the smallest system board of msp430 one and a half years ago, and I played with it a while ago. Now my company needs to develop a low-power circuit board, which is exactly what I need. So I a...

The ARINC429 bus is one of the most commonly used communication buses between various subsystems of avionics. As the "skeleton" of modern avionics systems, once the bus system or the attached airbo...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
This paper describes the design method of electronic multifunctional watt-hour meter, the key technology of hardware design and the software design process. Taking NEC's μPD78F0338 microcontroller ...[Details]
