The mathematical process of resolving a given function, f(x), into its frequency components, which means finding the sequence of constant amplitudes to plug into a Fourier series to reconstruct the original function.
A method of dissociating time series or spatial data into sets of sine and cosine waves.
A method of finding he frequencies (or periods) present in a time series by decomposing it in to a series of sine waves as demonstrated by the mathematician Fourier.
analysis of a periodic function into a sum of simple sinusoidal components
the process of using the terms of a Fourier series to find a function that approximates periodic data
The decomposition of a signal into its simplest harmonic curves (sines and cosines). Galaxy: A large system of stars. Our galaxy, the Milky Way, is a spiral galaxy containing some 100,000 million stars, 100,000 light years in diameter and 10,000 light years thick.
the method of analysis in which a complex wave is regarded as a suitable combination of a number of pure tones. a mathematical theorem that any periodic vibration can be analyzed into a set of single sinusoid waves. In turn, the superposition of the sinusoid waves will reproduce the original vibration. (H:552)
is a mathematical technique for turning a time series into a set of coefficients which are the amplitudes of a set of sine waves of various frequencies so that those sine waves add up to the original data.
A technique, usually performed using a DSP algorithm, that allows complex, dynamically changing audio waveforms to be described mathematically as sums of sine waves at various frequencies and amplitudes. See DSP.
