[font=宋体]He invented the integrated circuit, and his invention changed the world. He was a man of few words and modest. He remained true to his craft and adhered to scientific principles. He is gone. ...
Please help me analyze the operation of this circuit.There should be a sine wave output on the left side of R2, but I can't see it in the simulation. I don't know what the problem is....
This is mainly used to debug the G2452 RTC chip I made a while ago. I didn't have any ready-made tools, so I came up with this solution. I also learned about the USCI UART module by the way. In the en...
Under WINCE, I want to complete the CAN bus communication function by calling WIN32 functions, that is, get the handle of CAN1 through CreateFile(), and then perform send and receive operations by cal...
I have a device made with STM32F103VC. I used to use injection mode (all three ADs were used). The sampling zero drift was very small, basically within 1 LSB (most of them were 0). Now I use DMA mode ...
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
In the field of software development, the most critical but also the most unpredictable phase is the debugging phase. There are many factors that play a role in the process of software debugging, a...[Details]
The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communications since the advent of digital communications. Many new wireless commun...[Details]
In the issue of ensuring the safety of drivers and pedestrians, the proportion of electronic technology has increased. According to the survey, 80% to 90% of traffic accidents are caused by driver...[Details]
According to In-Stat/MDR, the number of mobile phones with Bluetooth capabilities will reach at least 300 million by 2005. One of the clear evidences of the increasing adoption of Bluetooth is that...[Details]
1 Introduction
Generally, when transmitting information over short distances through electrical signals, baseband signals can be directly transmitted. However, over long distances, baseban...[Details]
With the improvement of people's requirements for vehicle riding comfort and the development of passenger car suspension technology in my country, air suspension is increasingly used in passenger ...[Details]
This paper introduces the technology and application of optical transceiver modules and digital non-volatile variable resistors in optical communication networks, and focuses on the design and appl...[Details]
The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
Abstract:
The signal flow of the external transceiver in the WCDMA/TD-SCDMA protocol is analyzed. The analysis results show that most of the functional modules in the WCDMA/TD-SCDMA external tr...[Details]
The third generation iPhone, iPhone 3G S, has finally been released. Let's take a look at the differences in basic parameters between it and the previous generation iPhone 3G.
