In summary, the process of transferring multiple electrical signals of different frequencies over a wire is known as frequency division multiplexing and is commonly used in hardware. However, there is a more advanced version called orthogonal frequency division multiplexing which is used in technologies like ADSL. This technique involves using orthogonal carriers to transfer the signals and can be further understood through resources like the tutorial provided.

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.
 

1. How do signals transfer between neurons?

Signals transfer between neurons through the process of neurotransmission. This involves the release of chemical messengers called neurotransmitters from the sending neuron, which then bind to receptors on the receiving neuron, causing an electrical signal to be generated.

2. What is the role of synapses in signal transfer?

Synapses are the junctions between neurons where neurotransmitters are released. They play a crucial role in signal transfer by allowing for communication between neurons and ensuring that signals are transmitted in the correct direction.

3. Can signals be transferred between different parts of the body?

Yes, signals can be transferred between different parts of the body through a network of neurons and synapses. This allows for coordination and communication between different systems and organs in the body.

4. How do signals transfer in the nervous system?

In the nervous system, signals are transferred through a combination of electrical and chemical processes. Electrical signals, called action potentials, travel down the axon of a neuron. When they reach the end of the axon, neurotransmitters are released to continue the signal to the next neuron.

5. Can signals be transferred artificially?

Yes, signals can be transferred artificially through the use of technology such as brain-computer interfaces. These devices can interpret brain signals and translate them into commands that can control external devices or prosthetics.
