A Note on Cosine Power Sums
نویسنده
چکیده
where ⌊x⌋ denotes the largest integer not greater than x. Under certain conditions, these cosine power sums can be determined exactly, without approximations [5]. If f(x) = a0 + a1x+ a2x 2 + · · ·+ anx + · · · is a finite or convergent infinite series, then for 0 ≤ r < n the sum arx r + ar+nx r+n + ar+2nx r+2n + · · · is given by the multisection formula (see [1, Ch. 16], [4, Ch. 4, S. 4.3] and [6])

متن کاملMusic Transcription with ISA and HMM
We propose a new generative model for polyphonic music based on nonlinear Independent Subspace Analysis (ISA) and factorial Hidden Markov Models (HMM). ISA represents chord spectra as sums of note power spectra and note spectra as sums of instrument-dependent log-power spectra. HMM models note duration. Instrument-dependent parameters are learnt on solo excerpts and used to transcribe musical r...
متن کاملWeighted Divisor Sums and Bessel Function Series, Iii
On page 335 in his lost notebook, Ramanujan recorded without proofs two identities involving finite trigonometric sums and doubly infinite series of Bessel functions. The two identities are intimately connected with the classical circle and divisor problems, respectively. For each of Ramanujan’s identities, there are three possible interpretations for the double series. In two earlier papers, t...
