Dear experts:
I want to ask for advice. I want to make a vibration platform. The vibration platform drives 4 voice coil motors on 4 corners to perform different vibration modes. The frequency and ampl...
My boss thinks STM32 is more cost-effective. He chose it for a recent project. When STM32F103RD was just in the prototype stage, he found that several IO chips were not working properly. He thought it...

Maximize instrument utilization and reduce
test times
Increasing the throughput of automated test systems can improve efficiency. Using off-the-shelf tools (COTS) such as multicore proc...[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]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
As microcontrollers become less expensive and more powerful, electrical designers are finding it more cost-effective to use multiple small controllers in both single-board and multi-board systems. ...[Details]
Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[Details]
introduction
Like other
portable
electronic products,
blood flow parameter detectors
need to be small, thin, durable, reliable, and have a long standby time. Therefore, system desi...[Details]
In a Class D audio power amplifier, the preamplifier is a relatively important module. It is located at the front of the entire topology and completes the processing of the input signal source,...[Details]
Preface
For a long time, SD cards with Flash Memory as storage have been widely used in consumer electronic products due to their small size, low power consumption, erasable and non-volati...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure

Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
Lifting wavelet transform not only has the advantages of traditional wavelet multi-resolution, but also simplifies the operation and is easy to implement in hardware. Therefore, it is widely used in d...[Details]
1 Introduction
Intelligent software agents are software programs that can perform specific tasks for users, have a certain degree of intelligence, can autonomously perform some tasks, and ...[Details]
l Introduction
Traditional human-computer communication is achieved through keyboard or mouse. The speed of information exchange is relatively slow, and the operator is required to have certain...[Details]
Anyone who has owned a laptop computer will have noticed that when running on battery power, their portable device behaves differently than when running on AC mains power—the display dims, the proc...[Details]
