In high-speed digital signal processing (DSP) systems, electromagnetic interference (EMI) is a critical issue that cannot be overlooked. Due to the high-frequency signal processing and complex circuit layouts involved in DSP systems, the electromagnetic environment becomes more complicated, easily leading to signal distortion, system instability, and even functional failure. Therefore, engineers need to understand the … Read more
1. PCB Layout 1. Follow the layout principle of “big first, small later, difficult first, easy later”, meaning that important unit circuits and core components should be prioritized in the layout. 2. The layout must refer to the schematic diagram and place components according to the signal flow rules of the schematic. 3. The arrangement … Read more
