I know about the the shifting property of the impulse function in the time domain as can be seen in the picture.

But what is the effect of multiplication of a function by the impulse function in the Frequency domain.

ie: X(W) = δ(w - w0)*H(w) = ?

    $\begingroup$ Does this answer your question? What is the Effect of Multiplying a Function by the Unit Impulse Function in the Frequency Domain? $\endgroup$ – DSP Rookie Jun 9 '20 at 8:21
