Click the blue “Radar Journal” to follow Technical Background and Significance In radar training, teaching, and scientific research, practical radar equipment is often constrained by factors such as high costs, wear and tear, large size, and electromagnetic radiation control, making it difficult to conduct experiments based on real installations. Moreover, using real radar is limited … Read more
Introduction: In industrial automation control systems, PLC is one of the core controllers, while the servo system is an important part of achieving precise control. To enable the PLC to accurately control the servo motor, it is essential to ensure that the signals output by the PLC can be correctly recognized and executed by the … Read more
Paper Summary: Development Research of Three-Component Microseismic Node Instrument Based on ZigBee/WIFI/LTE Cat.1 1. Research Background and Significance Application Scenarios: Microseismic signals are widely present in coal mines, oil exploration, and bridge construction, used for monitoring rock stress changes, predicting disasters (such as rock bursts, collapses) and oil and gas reservoir distribution. Technical Challenges: Traditional … Read more
Microcontroller ADC and DAC Applications: Analog Signal Processing Examples Hello everyone, I am the female top laner. Today we will talk about analog signal processing in microcontrollers, focusing on the applications of ADC and DAC. These two modules can be considered important “translators” that connect microcontrollers with the real world. The ADC is responsible for … Read more
In daily work, many people often ask about the difference between CDR solutions and DSP solutions, especially in the context of QSFP56 200G SR4 and QSFP-DD 400G SR8 optical modules and their corresponding AOC series products. This article will detail the differences in functionality, principles, technical characteristics, application scenarios, and implementation methods of the two … Read more
▲ For more exciting content, please click on the blue text above to follow us! DSP can be traced back to the dawn of the digital age, possibly even earlier. If the construction of the first digital computer ENIAC in 1946 marked the beginning of the digital age, then DSP appeared two years later. In … Read more

Acoustic feedback is one of the most troublesome issues in live sound amplification. It can cause regenerated reverberation, severely affecting speech clarity, limiting the improvement of system gain, and causing distortion in sound. When feedback becomes severe, it can lead to self-oscillation, making the entire system unable to function properly and even damaging the speakers … Read more
