Main Question or Discussion Point

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.
