introduction
When we run or ride a bicycle, the vibration of our arms often makes the images displayed on the electronic devices in our hands look blurry. Long-term viewing (such as watchi...[Details]
introduction
Usually, there are many input and output ports in RF systems, and it is expensive to use a multi-port network analyzer to analyze scattering characteristics. Therefore, it is ...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
