7 commonly used interface types in circuit design

We know that there may be some problems when the various sub-modules of the circuit system perform data exchange, resulting in the signal not being able to “circulate” normally and with high quality. For example, sometimes the working timing of the circuit sub-modules deviates (such as CPU and peripherals) or their respective signal types are […]
