I am currently working on an experiment to connect DSP to AD5390. DSP controls AD5390 through SPI bus. Currently, writing DSP program is not a problem, but I am still having a headache on how to write...
This is my first time to do Fourier. Now I want to collect 125HZ and 225HZ signals. So what should my sampling frequency and sampling points be? Can you help me calculate it? It would be best if you c...

Copy the file. If the file exists, you can set it to overwrite or not. Currently, I use SHFileOperation. The compilation error is: error LNK2019: unresolved external symbol SHFileOperationW referenced...
Controller Area Network (CAN) is a type of fieldbus. It is a serial communication network that effectively supports distributed control or real-time control and is recognized as one of the most pro...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[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]
As the whole equipment is becoming increasingly miniaturized and power-saving, low-dropout linear regulators (LDOs) with low power consumption are becoming the mainstream in the market for linear regu...[Details]
Overview
Currently, many portable consumer electronic products, such as mobile phones, PDAs, MP3 players, and notebooks, are equipped with display screens. Although the type and size of the di...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[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]
Electrocardiogram is an important means of diagnosing heart disease. However, due to various reasons, it is difficult to capture abnormal electrocardiograms with ordinary electrocardiographs. Although...[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]
introduction
Image compression technology is becoming more and more important in modern life. With the improvement of data processing speed of DSP, a single-chip DSP can achieve good results...[Details]
Abstract: This paper uses the S3C2410 chip GX development board with ARM920T core as the hardware platform and Windows CE operating system to design an embedded system touch screen interactive func...[Details]
Preface
In the application of PLL, DLL and CDR circuits, people generally require the output clock signal to have a 50% duty cycle so that data can be sampled at both the rising and fallin...[Details]
When it comes to ATX power supply, people will think of two "classic" ICs: pulse width modulation chip TL494 and voltage comparator LM339. The new dedicated control chip AT2005B has the functions ...[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]
