How far does the delocalisation (resonance) effects for substituents extend for a conjugated system?

Let's say we have a conjugated system like this one:


[![4-nitro-(E)-stilbene](https://i.stack.imgur.com/WrteN.jpg)](https://i.stack.imgur.com/WrteN.jpg)


Now, the delocalisation of the benzene electrons with the nitrate system means that the ortho, and para positions on the immediate benzene ring would be more electron deficient than the meta position. This effect will be seen in 1H NMR and 13C NMR signals for the protons or carbons on the ortho/para/meta position. Also, the electrophilic substitution on those positions will be affected.


Now as I understand, the resonance effects of the $\ce{-NO2}$ group is due to the overlap of N 2p orbitals with the benzene ring p orbitals, which skews the sizes of molecular orbitals, and makes certain carbons more electron-deficient than others.


However, are resonance effects independent of distances over which they act? I am not sure if distance would have any role on the skewing of the molecular orbitals.


Does the distant benzene ring, and the double bond in between also show the resonance effects from the nitro group on the first ring? If so, is it as strong, or is it weaker? Can this be seen in NMR spectra? or the reactivity of the distant benzene ring?
