AI Thread Summary
Optodecoders, optoencoders, optocouplers, and optoisolators are essential components in electronic circuits that utilize light for signal transmission and isolation. Optodecoders and optoencoders convert optical signals into electrical signals and vice versa, enabling data processing and communication. Optocouplers provide electrical isolation between different parts of a circuit while allowing signal transfer, protecting sensitive components from high voltages. Optoisolators serve a similar function, ensuring safety and preventing interference in electronic systems. For detailed explanations and diagrams, resources like Wikipedia can provide comprehensive information.

I need detail explanation and if possible diagrams on optodecoders,optoencoders,optocouplers and optoisolators.

thank you.

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
