Specific frequency signal from a wide range of signals from a decoder

AI Thread Summary
Separating a specific frequency signal from a wide range of signals is achievable using filters, which are essential components in electrical engineering. Filters can be analog or digital and are designed to isolate desired frequencies, such as 60Hz from a range of 1Hz to 100KHz. Various types of filters exist, each suited for different applications and requirements. Understanding the characteristics and functions of these filters is crucial for effective signal processing. Filters play a fundamental role in managing and decoding signals in various electronic systems.

Is it possible to separate a specific frequency signal from a wide range of signals from a decoder/demux. For an example if you had a frequency range from 1 hertz to 100 KHz, is it possible to separate a signal of let's say 60Hz from the other signals.

The appropriate circuit is called a "filter." There are a veritable zoo of different kinds of filters, both analog and digital, and they are one of the building blocks of all electrical engineering.

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...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
