전자 공학자에게 가장 적합한 오실로스코프: 개인용 vs. 전문 실험실 장비
Introduction An oscilloscope is one of the most important instruments for electronics engineers. It allows you to observe electrical signals over time and investigate problems that cannot be diagnosed easily with a digital multimeter alone. Whether you are a hobbyist building electronic circuits, an embedded engineer debugging a microcontroller, or a professional working in an […]
PCB 접지 설계: 노이즈, EMI 및 접지 반사 감소 방법
Introduction One of the most important parts of PCB design is also one of the most frequently misunderstood: Ground. Many engineers initially think of ground as simply a connection to 0 V. In a real PCB, however, ground is also a current-return path. When current flows through a PCB trace, plane, via, connector, or cable, the resistance […]
PCB Ground Plane: Why It Matters for Signal Integrity and Power Stability
When designing a PCB, engineers often spend a lot of time thinking about signal traces and power traces. However, there is another path that is equally important: The return current path. A signal does not simply travel from one component to another and disappear. Current must complete a loop. For many PCB designs, a properly […]
