    How do you calculate cross and auto-correlation in time and frequency domains?

    1. Okey, then the lag should be 2 in this case? Because there are two zero values before the first non-zero? And since the sampling time is 1ms then the time difference would be 2ms? 2. That would be integral of [f(t)*e^(-jwt) dt] where f(t) is the correlation function. Although I'm not sure...

    How do you calculate cross and auto-correlation in time and frequency domains?

    Homework Statement 1. Given two vectors x = [0 0 1 0 0 ] and y = [0 0 0 0 1] find the cross correlation and the time difference between the pulses if the sampling frequency is 1kHz? 2. Given this vector calculate the auto correlation and if the signals is sampled at a frequency of 1MHz...

    Measuring Voltages Across 10k, 100k, 1M & 4.7M Ohm Resistors

    Thanks for your replies! Lets assume that we knew that it wasn't an ideal voltmeter, how would you find the internal resistance? I think that is the part I'm not understanding

    Measuring Voltages Across 10k, 100k, 1M & 4.7M Ohm Resistors

    Homework Statement We are supposed to figure out the voltages over every resistance when measuring with a voltmeter Homework Equations R1=R2=10k ohm R3=R4=100k ohm R5=R6=1M ohm R7=R8=4.7M ohm U=10V The Attempt at a Solution The thing I'm not quite...

    Electric field of a coaxial cable

    We have a coaxial cable with inner radius a and outer radius b. The coaxial cable is modeled as two very long circular metal cylinders. I'm supposed to calculate the electric field E, the electric potential V and the charge enclosed Q when a voltage is applied between the metal cylinder...
