hi everyone
i have a set of complex valued vectors which i want to perform principal component analysis on. so my data matrix will be all the vectors putten as columns of the matrix beside each other where the number of components of each vector is 10 and the total number of vectos is 1000, so...
hi everyone
i am looking for a for a robust speech voicing detection (voiced / unvoiced) algorithm for speech signals , can someone help me in this please ? infact for what reason i dont know all the pitch extraction algorithms i 've found has peculliarly assumed of the input signal to be...
How to write matrix form of relationship between details of wavelet packet at scale j and details at scale j+1. If it is desired to apply matrix form of representation for determining details at different frequency bands , write the necessary matrix equations. Write an example of such a relation...

calculate efield from loop
how to calculate the electric field intesnity and direction around a loop with uniformly distributed charge and radius r, at any point in space NOT necessarily only along its Axis !!! it reduces to unsolvable integrals in my ways, does anyone know the shortest and...
about integral ..?
hi everyone
does anyone knows what is the answer of this indefinite integral ?
dx
----------------------- = ?
( a + b*cos(x))^.5
thnx
Re: what is voiced speech ?!
thanx but can u make it a bit more clear ? infact if it is as u just said then is this a true inference ?
vowels = voiced speech Consonants = unvoiced speech
tell me if i am wrong
what is voiced speech ?!
hi everyone
would someone please explain me explicitely that what is "voiced speech" and what is its difference to "unvoiced speech" ? i mean wull, speech is produced by voice, i dont understand it anyway !
thnx
hi all
could someone please explain me the the following problem ?
the fact is i dont understand that why the fuzzy logic is called a different and independent topic on its own ? actually i think that fuzzification i just a sort of nonuniform , smart quantization based on some sort of...
i mean any signal that has finite bandwidth in both frequency & time Domains.
imagine a simple Pulse with finite duration & its transform Sinc function, although it is finite in time but not in frequency. i should note that by finite , i mean exactly & strictly finite ! just like the pulse...
hi everyone
i am wondering wether there exists signals limited both in time and frequency domains or not. actually i have been told by one of my professors that there is some. but i cant even imagine it ! could some one give me some examples : 3 at least ?
Regards
Re: planck's constant
The first instance of an absolute in nature that impressed Planck deeply, even as a Gymnasium student, was the law of the conservation of energy, the first law of thermodynamics. Later, during his university years, he became equally convinced that the entropy law, the...
