▲ 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
The DSP video tutorial hasn’t been updated for a while. Currently, the DSP library has been separated from the CMSIS software package and is being updated very frequently. Therefore, this episode of the video tutorial will first give a brief introduction to the new DSP version, and then provide a detailed introduction to the basic … Read more
Introduction The currently popular MCUs mainly fall into two categories: ARM and DSP. Among the many manufacturers of DSP, TI (Texas Instruments) is one of the important leaders in the DSP chip field. CCS is an integrated development environment (IDE) software designed for Texas Instruments (TI) processors and microcontrollers. CCS provides developers with a complete … 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
