Which only to thunder's lips is known,
And the earth held up her fearless face
And listened as if to a signal blown,--
A signal-trump in some heavenly place.

Swells the blast of the bugle, that summons to prayer:

In science:

Thus, in all the examples presented so far the node signals actually employed by the Wiener Filter are the signals corresponding to nodes directly connected to the node signal being estimated.
A Reconstruction algorithm for an unknown network
In this case the Wiener filter estimating x0 from the other signals makes use not only of the signal x2 which is directly linked to it, but also of the signal x1 which is not.
A Reconstruction algorithm for an unknown network
If the GW emission is accompanied by electromagnetic (EM) emission (such as the case of a corecollapse supernova or a white-dwarf binary), a bound on the mass of the graviton can be placed by comparing the time of arrival of the GW signal with the EM signal , or, by correlating the EM and GW signals [11–13].

A digital interface for Gaussian relay and interference networks: Lifting codes from the discrete superposition model
The communication channels are wireless; transmitted signals from a node are broadcasted to all other nodes; received signals at a node is a linear superposition of the transmit signals with a random additive noise, which has the familiar Gaussian distribution.
