    Rf signal question, frequency domain represntation at stages through quadrature mixer

    Consider the quadrature mixer as shown below. The frequency domain representation of the input signal x(t), X(f) is as shown below. Assuming that f2>>f1>>fb, draw the frequency domain representation of the signal at points a, b, c, d and e. I am not asking you to do this for me. I would...

    Fourier Transform question

    I am supposed to find the Fourier transform of . I calculated it as E= aEoΠ[e-jφδ(w+wo)+ejφδ(w-wo)]. Is this correct?

    Use Taylor series to show that the truncation error for the Yee’s FDTD method

    I believe this is the expansion but what more am I supposed to show?

    Use Taylor series to show that the truncation error for the Yee’s FDTD method

    uhhh no. I thought this was a homework (non hyphenated) section.

    Use Taylor series to show that the truncation error for the Yee’s FDTD method

    Use Taylor series to show that the truncation error for the Yee’s FDTD method in a one-dimensional staggered grid is O(Δt2)in time and O(Δx2)in space.

    Boost Converter, Relate VLoad to Vin as a function of duty ratio

    Derive the relationship between load voltage, Vload, and the input voltage, Vin, as a function of the duty ratio of S1. I know it should be similar to that of a basic boost converter but I do not know how to derive either of them. The boost converter I know of has Vout =[Vin*Ts]/[(1-D)*Ts] or...
