((Only 14, 15, 16 please ))
The system given by the difference equation y[n] = + x[n - 1] has the following impulse response If x(t) = e^j0.5 pi t then the generalized Fourier Transform of y(t) = d/dt x(t) is: a. Y(j omega) = j0.5 pi delta(omega - 1) b. Y(j omega) = j omega pi delta (omega - 0.5 pi) c. Y (j omega) = j0.5 pi delta (omega + 0.5 pi) d. None of the above The frequency response of the system whose impulse response is given as h[n] = delta[n] - delta[n - 1] is: b. A periodic discrete function c. A periodic continuous function d. A non-periodic continuous function e. A non-periodic discrete function The continuous time function x(t) with the frequency coefficients X[k] = 1 - cos(pi k)/(pi k)^2, is: a.
