Digital signals are fundamentally electromagnetic waves added together. The higher the data rate required, the higher the frequency of the waves required to generate the signals. Once the signal ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

In power supplies, dc-dc converters and many other power electronics circuits, chokes and transformers form an essential part of the filter network that provides low-ripple dc power. In many designs, ...
