Or one could consider the roles swapped. -The term "ambient frequency" refers to the aggregate of background signals present in a given environment. In urban contexts, this includes electromagnetic interference from power infrastructure, wireless communications networks, and consumer electronic devices. The ambient field is not centrally coordinated. No single source generates it. It emerges from the cumulative output of many transmitters operating within similar parameters. The resulting noise floor is persistent and of low significance under normal circumstances. Signals that fall below this threshold remain technically present but are not distinguishable from the noise itself, and are not considered practially receivable. +The noise floor of a receiving environment is the aggregate of all background signal energy present across a given frequency band at any instant. In urban contexts, primary contributors include electromagnetic emissions from power distribution infrastructure, wireless communications networks, and consumer electronic devices. The noise floor is not centrally coordinated; no single source generates it. 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. Under standard conditions, this background level is treated as a fixed baseline rather than a variable of interest. 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. -An impulse signal, sometimes referred to as a unit impulse, is defined as a signal with zero amplitude at all points except for a single instant, at which point its amplitude approaches infinity while its total energy remains finite. In practical applications, true impulse signals cannot be generated; they are approximated by short-duration waveforms of high amplitude. The impulse response of any linear system - that is, the system's output when presented with an impulse input - fully characterises that system's behaviour. From a single impulse and its response, the complete identity of the system can be derived. This property is considered fundamental to signal analysis. +An impulse signal, also referred to as a unit impulse, is defined as a signal with zero value at all points in time except a single instant, at which its value is notionally unbounded, subject to the constraint that its total integrated area equals unity. In practice, true impulse signals cannot be physically produced; they are approximated by short-duration, high-amplitude pulses of sufficient bandwidth. 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. 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. From a single impulse and its measured response, the complete transfer function of the system can be derived. This property is considered foundational to systems analysis. // build some tension with bass and drum and fiddle here
