    integration in matlab help plz........

    You also need the field direction. The magnitude alone, does not specify the field completely. Added after 3 minutes: By the way, if have the field completely, you can compute the voltage difference regardless of the integration path because of we know that the integration of E on a close...

    What's the application of PSD and ESD?

    psd and esd signals The stochastic processes that we encounter are always considered stationary, and it can be proved that all stationary processes are of the power type. Therefore, the PSD is common.

    how does fourier transform transforms time to freq domain

    Re: how does fourier transform transforms time to freq domai in the fourier transform integral, the limit on t is from -inf to +inf. therefore the t parameter is not present in the result, and only f remains.

    problem regarding decimation of samples

    It depends whether the sampling rate used is above 4 time the nyquist rate or below. If it is above, dropping three samples out of four, wont cause a problem.

    What is Sigma-Delta Modulation?

    In sigma delta, the main Idea is adding an integrator to the beginning of the delta modulator to decrease the slope overloading effect. Added after 1 minutes: By the way, the best thing about it is the simplicity at the receiver. In fact, the receiver is simply a low pass filter.
