AI Thread Summary
Frequency Division Multiplexing (FDM) allows multiple electrical signals of different frequencies to be transmitted over a single wire by dividing the frequency spectrum into distinct channels. The implementation of FDM in hardware typically involves using filters and modulators to separate and combine signals. Orthogonal Frequency Division Multiplexing (OFDM) is an advanced form of FDM that utilizes orthogonal carriers to improve efficiency and reduce interference. Resources like the provided tutorial explain the technical details of OFDM's implementation. Understanding these methods is crucial for effective signal transmission in various communication systems.

how do we transfer many electrical signals of different frequency over a wire?

i know its called frequency division mutiplexing, but i want to know how it is implemeted on hardware.

There is a better thing called, orthogonal frequency division multiplexing, your ADSL.

Take a look at this. It explains in-depth the implementation of such division. The only difference between this one and you mentioned is that carriers are orthogonal to each other.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
