Help with Hertz and BPS in communication channels

AI Thread Summary
BPS refers to bits per second, indicating data transfer speed, while Hz denotes bandwidth, related to the frequency of oscillations in communication channels. Higher frequencies can transmit more information, but bandwidth and frequency are not the same; the relationship depends on how the information is encoded. For effective signal transmission, the frequency should be at least ten times greater than the number of pulses per second to ensure clear signal representation. Understanding these distinctions is crucial for effective communication channel analysis. The clarification provided aims to resolve confusion regarding these terms in the context of UTP and coaxial cables.

Hi, I am researching communication channels such as UTP, coax etc and I keep seeing them referred to with either M/k/G bps and MHz. Am i correct in thinking bps is the data transfer speed and Hz is referring to bandwidth as I am getting confused? Thanks

Hz is usually referring to harmonic oscillations. 1 Hz is one full oscillation per second. Like a pendulum - from center to left and then back to right, and then back to center. If pendulum makes it 2 times per sec it will be 2Hz.

In radio Hz are referring to a base frequency that may be modulated some way (amplitude, phase, etc) to transmit an information signal.
Higher base frequency may transmit more information signal, so bandwidth is correlated with base frequency. But it is not same. Rate of bandwidth to base frequency depends on a way of coding information signal into base frequency modulations.
 
I am not 100% certain about your question but... I think BPS means bits per second, ie pulses per second and MHz refers to the frequency of the transmission (radio etc)
One guidline I am aware of is that to produce 'good' sharp pulses the transmitting frequency needs to be at least 10x greater than the required number of pulses per second.
This is so that each pulse can contain at least 10 cycles of the transmitting wave.
Very basic...hope it helps.
 
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...
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...
