What are the general principles of anti-interference?
The general principles for increasing the anti-interference capacity in Printed Circuit Boards (PCBs) include inhibiting interference sources, cutting down interference transmission paths, and enhancing the anti-interference capacity of sensitive components. The solution is often to enlarge the distance between the interference source and sensitive components or isolate them through ground wires.
What is anti-interference in PCB design?
In the process of PCB design, designers must conform to the generic principles of PCB design and the requirement of anti-interference. The ability of anti-interference in PCB design has a direct relation to the validity and stability of electronic products, even regarded as the key point of design.
What are the anti-interference components?
Anti-interference components such as Ferrite bead, Ferrite tube, power filter, and shielding case are used on some key places on the board like SCM I/O ports, power wires, and PCB connecting lines to drastically increase the anti-interference capacity of the circuit.
How does a capacitor work?
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
Is passive anti-aliasing effective in a switched-capacitor filter?
This is generally effective when the switched-capacitor filter is performing a low-pass or band-pass function, but it may not be practical with high-pass or notch filters because the passive anti-aliasing filter will reduce the passband width of the overall filter response.
What is the anti-noise ability of electronic circuits?
The anti-noise ability of electronic circuits. There are logic circuits and linear circuits on the PCB so that they should be separated as much as possible. The low-frequency circuit can be grounded in parallel at a single point. The actual wiring can be connected in series and then grounded in parallel.
EMI Filter : Types, Circuit, Working & Its Applications
There are two types of electromagnetic interference conducted & radiated. The conducted type EMI travels through conductors like power lines or wires whereas radiated types EMI goes through the air & does not need a conductor. These two EMIs can affect the performance of the electronic device through degradation, impairment, system failure, or malfunctioning.
