The signal flow diagram for a certain feedback control system is shown in figure Now consider the following set of equations for the nodes 1. x 2 = a 1 x 1 + a 9 x 3 2. x 3 = a 2 x 2 + a 8 x 4 3. x 4 = a 3 x 3 + a 5 x 2 4. x 5 = a 4 x 4 + a 6 x 2 Which of the following are correct? Which of the following is not the modulation technique If there are sign changes in the first column of Routh's array, the system is A finite duration discrete-time signal x(n) is obtained by sampling the continuous-time signal x(t) = cos(200πt) at sampling instant t = n/400, n = 0, 1, . . . , 7. The 8-point discrete Fourier transform (DFT) of x(n) is defined as $$X\left[ k \right] = \sum\limits_{n = 0}^7 {x\left[ n \right]{e^{\frac{{ - j\pi kn}}{4}}},\,k = 0,\,1,\,.....,\,7} $$ Which one of the following statements is true?
