So, so I'm going with a rusty knowledge of a computer engineering course from years ago,

What do you mean by this?

But each slice is multiplied by an exponent.. which, okay, becomes a convolution that lets you recover the original function

Like how the DC term of Fourier transform is the baseline average, i.e. global energy constant (per time), the baseline decay describes the global energy dissipation or amplification (per time).
