For example, if you hear of this when you talking about fading stuff, 'coherent frequency' would mean As I said, the word 'something' would have different meaning depending on situation. A method for measuring the atmospheric coherence time, which now in routine use in the Sydney University Stellar Interferometer (SUSI), is described and som. ![]() If you hear of this when you talking about fading stuff, 'coherent time' would mean 'a certain time span during which the fading property remain unchanged'.Ĭoherent frequency : Same logic, It means a certain span of frequency during which 'something' stays same. So in this case, the Coherent time would mean 'a certain time span in which the phase delay of traveling wave does not change. For example, if you heard of this when you are talking about some traveling wave (propagating wave), the "something" As I said, the word 'something' would have different meaning depending on situation. It would mean different things depending on situation (context).īased on this, you can derive the meaning of some of common terminology you would hear or see in various materials on communication theory.Ĭoherent time : It means a certain span of time during which 'something' stays same. It mean 'Something stays same (does not change)'. Without clear understanding of this words, I got confused with many other terms that came from this word, like 'Coherent time', 'Coherent Channel', 'Coherent frequency' etc. To me, the word 'Coherence/Coherent' is one of those words. Sometimes, we see some word that sound like simple, but hard to get clear understanding. Coherence/Coherent Time/Coherent Frequency ![]()
