An oscilloscope is a window to observe waveforms, allowing designers or maintenance personnel to see electronic waveforms in detail, achieving a real-time visual effect. Because the human eye is the most sensitive visual organ, it can perceive minute details and quickly reflect objects to the brain for comparison and judgment. According to the different classifications … Read more
Abstract: In order to solve the difficulty of feature extraction in analog circuits fault diagnosis and to accurately classify fault pattern, a new analog circuit diagnosis method based on the combination of optimal wavelet basis, fuzzy theory and self-organizing feature map is proposed. The response signals of the analog circuit are preprocessed by wavelet transform … Read more

Introduction In Rust, memory management is a very important task. Rust helps developers avoid many common memory issues through mechanisms such as ownership, borrowing, and lifetimes. However, Rust also provides some smart pointers for handling heap-allocated memory, which not only simplify memory management but also give us more flexibility. This article will detail several smart … Read more
[Image] There are many ways to classify chips. If we randomly interview 10 industry leaders, we might get 10 different answers. For example, based on the way signals are processed, chips can be divided into analog chips and digital chips. According to design philosophy, they can be classified as general-purpose chips and special-purpose chips. Depending … Read more
This article guide The RS-485 bus is a half-duplex communication bus, so it usually requires an MCU to control the transmit/receive state of the RS-485 transceiver. To save MCU I/O resources, RS-485 automatic transceivers have emerged, but these types of transceivers encounter some application issues to varying degrees. How can these issues be resolved? This … Read more
