Filter insertion loss characteristics, network impedance determination

The differential mode insertion loss of the filter has a great relationship with the network impedance to which the filter is connected. 99% of filter manufacturers only provide curves A and B, but not C and D. The selection of the filter by the manufacturer's curves A and B alone does not guarantee that the test will pass.

Teach you to apply linear filters on real image data

Teach you to apply linear filters on real image data

Convolutional neural networks typically learn useful features from training data. The features learned by the first convolutional layer are often the basic elements of some training data depending on the task. For example, in the image data, the learned features may embody edges and blobs. In subsequent network layers, these learned features can represent more abstract, more advanced features.

Definition of Inductors

Definition of Inductors

Inductance is the ratio of alternating magnetic flux generated in and around the wire when alternating current passes through the wire, and the magnetic flux of the wire is the ratio of the current that produces this magnetic flux.

Inductance coil and transformer

Inductive coil: When there is a current in the wire, a magnetic field is established around it. Usually we wind the wire into a coil to enhance the magnetic field inside the coil. The inductance coil is made by winding the wire (enameled wire, yarn bag or bare wire) on the insulating tube (insulator, iron core or magnetic core) by one turn (the wires are insulated from each other). In general, the inductor has only one winding.
