[01:23.91]The equilibrium of silence between the static magnetic noise, the watery planes, and the optical waves.

[01:44.25]Distant stations estimated in abnormal heat perform the inconsistent collimation rite.

[01:56.03]The black screen of stalemate conceals the massive stars, the charred comets, and the meteorites.
[02:04.45]Their questionable glitters, once emissions of brave borderers and dark adventurers,
[02:11.56]now the only traces, obscured and indifferent to all but those with a special breed of faith.

[03:27.90]The noise floor of a receiving environment is the aggregate of all background signal energy present across a given frequency band at any instant. 
[03:37.14]In urban contexts, primary contributors include electromagnetic emissions from power distribution infrastructure, wireless communications networks, and consumer electronic devices. 
[03:50.85]The noise floor is not centrally coordinated; no single source generates it. 
[03:56.21]It emerges from the cumulative output of many independently operating transmitters, each functioning within its own parameters, whose combined effect is persistent and largely uniform. 
[04:08.45]Under standard conditions, this background level is treated as a fixed baseline rather than a variable of interest. 
[04:16.56]Signals whose amplitude falls at or below this baseline remain physically present in the medium but cannot be distinguished from the background by a receiving system, and are not considered recoverable.

[04:32.10]An impulse signal, also referred to as a unit impulse, is defined as a signal with zero value at all points in time 
[04:40.26]except a single instant, at which its value is notionally unbounded, subject to the constraint that its total integrated area equals unity. 
[04:51.22]In practice, true impulse signals cannot be physically produced; they are approximated by short-duration, high-amplitude pulses of sufficient bandwidth. 
[05:04.06]The impulse response of any linear time-invariant system — that is, the output produced when an impulse is presented as input — fully characterises that system's behaviour under any subsequent input. 
[05:17.81]In the absence of any input, a system at rest produces no output and exhibits no properties that distinguish it from any other inactive system. 
[05:27.34]From a single impulse and its measured response, the complete transfer function of the system can be derived.
