    Long time? not as long as we have had radiation from the sun :)

    EMP question (MW2 spoilers)

    It is a pulse and thus has a broad frequency content. The amount of energy you can pickup will also depend on the energy in the incident wave. At the same location, a device inside a house is less exposed than one outside of it. If the level of exposure is sufficient to cause damage depends on...

    Question about CSFT (2d FFT)

    There is a difference between a sequence of numbers, and samples of a function, cos while both can be represented by a set of numbers, the sampling interval is relevant in one case and not the other. If I give you a finite set of of numbers, you can compute the DTFT with it, but you cannot...

    Question about CSFT (2d FFT)

    its not a matter of interpretation or choice of domain. For example, an essential part of defining the fourier series equivalent expression is the associated fundamental frequency, which is not relevant in the case of the DTFT as the range is normalized. If one ignores such differences, one...

    Question about CSFT (2d FFT)

    @OP exp(2*pi*x*u0)*exp(2*pi*x*v0) will give you an impulse at (u0, v0) or at its image, depending on how you define your foward and inverse transforms. Changing u0 and/or v0 will move the impulse accordingly in the (u,v) plane. Interpretation of the location of an impulse will depend on the...

    Question about CSFT (2d FFT)

    While the expressions are similar, a DTFT is not an inverse Fourier series, as a Fourier series is based on continuous time while a DTFT is a forward transform on discrete time. In addition, for DTFT, the frequency range is bounded by f= [-1/2, 1/2] or a similar range. A DFT is a DTFT with...

    Question about CSFT (2d FFT)

    CSFT = Continous Space (not surface) Fourier Transform. Continous Time Fourier Transfrom (CTFT) and Discrete Time Fourier Transform (DTFT) operate in two differnt domains. FFT is an algorithm for computing DTFT.

    Interpretation of Square wave response

    The Fourier series of a triangular waveform is also made up of odd harmonics. http://mathworld.wolfram.com/FourierSeriesTriangleWave.html The Fourier coefficients for a square wave are proportional to 1/n,where n is the order of the harmonic.

    Regular expression property

    arent all 3 expressions simply equal to (R|S)*

    Regular expression property

    are R and S sets or elements? and '*' = kleene?

    Phasor analysis

    Another reason for it being pointless is that there will be only two phases (0 and pi) and thus all your phasors will lie on one line resulting in simple addition and subtraction

    CPU Overclocking, Vcore MAX myths and truth

    Nice discussion. My understanding of the issue is that with LLC you are essentially trading a higher V_load (and lower V_idle), for higher transient overshoot. I expect the actual calibration to be a one time even, but that does not exclude the occurrence of transients with load changes...
