    Fortran Fortran 90, changing 8 bit stream into a 10 bit one

    Thank you very much for your help so far. I'll try that out and see if it works. Kind regards, Marko

    Fortran Fortran 90, changing 8 bit stream into a 10 bit one

    Happy new year, sorry for the late reply. Thank you very much for the detailed explanation. How would i go about reading the file as a bit sequence?

    Fortran Fortran 90, changing 8 bit stream into a 10 bit one

    Maybe a bit more clear would be to write it like this. Instead of reading it like: 00001111 00001111 0000111... I would like to read it like this: 0000111100 0011110000 111...

    Fortran Fortran 90, changing 8 bit stream into a 10 bit one

    When reading data from a binary file, i only know how to read it in 1 byte chunks. The file's header is written in this format (first 6198 entries), but the rest of is in 10 bit format. That is why i opted for transforming the 8 bit stream into a 10 bit one, and then calulating the int...

    Fortran Fortran 90, changing 8 bit stream into a 10 bit one

    Hello, I'm having a bit of trouble converting an 8 bit stream into a 10 bit one. First i create intvalbin8, a Nx8 zero/one array where N is the byte length of the input data: (6198 is the header offset factor) j=1 do while (intvalout(i).gt.0)...

    Analyzing a Pulse: Averaging Spectra & Data Window Criteria

    I'll be honest and say that i am not following everything you've said but at least you gave some pointers. And to be direct my problem was determining the amplitude response for a horizontal seimograph. In the picture on the left is the one obtained by forcing it with a current(via...

    Analyzing a Pulse: Averaging Spectra & Data Window Criteria

    Well,i didn't expect this much information :) ... but of course,your observation is very much correct. I had some assignments for class and i just wanted to know,on a whim,why these methods are suited for my task. MATLAB help points to the Introduction to Spectral analysis from Stoica and...

    Analyzing a Pulse: Averaging Spectra & Data Window Criteria

    Is this method good for analyzing a pulse? Why is the averaging of the spectra good for noise cleaning? What's the criteria for defining how much windows in a set of data one should take? Anyone who clarifies this has a big thanks from me.

    Transmission of force(elasticity)

    I'm sorry if i wasn't clear enough,but my problem was the general solution to the equation of the scalar potential.I can see the analogy with,for an example,the problem of electrostatics: \nabla\vec{E}=4\pi\rho But i wanted to learn the mathematics behind it,which is impossible because,as...

    Transmission of force(elasticity)

    Studying from Love's Treatise on elasticity I am having some difficulties. For an isotropic body under the influence of a force within a finite volume T equiations of equillibrium via Hooke's law are given by : (\lambda + \mu )(\frac{\partial}{\partial x},\frac{\partial}{\partial...

    PDE Wave Equation/boundary condition question

    im sorry if I am doing wrong by posting in a another thread,but i have a similar problem... its an infinite string which is straight ( U(x,0)= 0) and has input velocity defined by some arbitrary function g(x)... from this conditions i have to derive...
