Convolution of Signals: High & Low Frequency Effects

AI Thread Summary
Convolving two high frequency signals will generally yield a high frequency output, while convolving two low frequency signals results in a low frequency output. When convolving a high frequency signal with a low frequency signal, the result depends on the similarity of the signals; if they share little in common, the output will be close to zero. Convolution is similar to correlation but involves reversing one of the signals. Understanding convolution is essential for analyzing signal interactions in various applications. The discussion clarifies the concept of convolution and its effects on signal frequencies.

Will we get a high frequency signal from convolving 2 high frequency signals?

Also will we get a low frequency signal from convolving 2 low frequency signals?

How about convolving one low and one high frequency signal? My intuition tells me its low frequency signal.

Thanks for any guidance on this

I don't know the word "convolve" and it isn't in my dictionary.

Do you mean "mix" or "mixing" ?

do you know what "convolution", as applied to signals, is?

anyway, to answer the OP, if you convolve a high frequency signal against a low frequency signal, if the two signals have little in common, what you'll get out is close to zero. convolution is the same as correlation except that one of the signals is reversed.
 
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...
