Abstract: Modern signal processing systems usually require high-speed data communication between different processors. The SRIO protocol is widely used due to its high efficiency and low latency. This
Dear teachers, how do you choose the filter capacitor for the bridge rectifier circuit?
When calculating the filter capacitor after bridge rectification, it is often necessary to first set a time cons
This kind of signal appears during simulation, like oscillation. The actual circuit built also has this problem. It looks like the noise is very loud, and I can't find the reason. This kind of signal
