Multiplying the polynomials would, as you say, convolve the coefficients. The convolution formula says the weight at some point in time is the product of the weights of the delays that, combined, would shift us to this point in time. | |

Feb 9, 2016 at 8:25 | comment | added | Ryan | The coefficients would be the discrete convolution of $x[n]$ and $h[n]$ (we did this as an exercise in class). I don't quite see what you're getting at though. | |
