Convolution of Signals: High & Low Frequency Effects

Click For Summary
SUMMARY

Convolution of signals involves the mathematical operation that combines two signals to produce a third signal. When convolving two high frequency signals, the result is a high frequency signal, while convolving two low frequency signals yields a low frequency signal. Convolving a high frequency signal with a low frequency signal typically results in a signal close to zero if the two signals share little in common. This process is analogous to correlation, with the distinction that one of the signals is reversed during convolution.

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.
