To show their respect for him, the British lawmakers asked a fine artist, Graham Sutherland, to paint Winston Churchill's picture. When it was completed, it was presented to him, at a grand affair in the Westminster Hall, at the House of Commons (下议院).There is a famous film that shows Churchill accepting the gift. He describes the painting as "a remarkable example of modern art", which draws loud laughter.In fact he must have been unhappy with the painting. Sutherland later reported that he asked whether it was to be painted with a "happy" or "angry" attitude. "Angry," replied Churchill. At the time, Churchill was coming to the end of his political life and was unhappy that people wanted him to end his career.Some twenty years later it was revealed that Lady Churchill hated the painting so much that she had it destroyed. "It was preying on (折磨) his mind," she was reported as saying.A leading art critic was asked what he thought about the matter. He said he could understand Lady Churchill and had pity on her. Graham Sutherland was a very honest artist, who could only paint what he saw. At the time it was painted, Churchill was an old man, worried by the thought that he would have to end his political career soon. But Lady Churchill shouldn't have had the painting destroyed. It could have been stored away until after their deaths.1. Why did the British lawmakers ask Graham Sutherland to paint a picture of WinstonChurchill?a. To show their respect to himb. To make Churchill happy.c. To put it in the Westminster Hall.d. To make Churchill unhappy.2. 省略3. 省略4. 省略5. 省略。

A region of convergence isnext to the worm holethe area of the z plane where stable poles are foundwhere a z transform existsa product offered by all DSP vendors3. When the expression 1 + (2z)-1 + (2z)-2 + (2z)-3 + ... converges, it equals1 + 0.5z-1z/(z-0.5)1/(1-2z)none of the above4. 1 - 0.2z-1 + 0.04z-2 - 0.008-3 + ... = z/(z+0.2). The region of convergence of this z transform is|z| > 0.2|z| > 0|z| > -0.2all z5. The z transform of (0.8)n sin(n3p/7) isz/(z - 0.8)0.975z/(z2 - 0.445z + 1)0.8z/(z2 - 0.429z + 1)0.78z/(z2 - 0.356z + 0.64)6. The z transform of 4u[n-5] +6u[n-8] equals4z-5/(z-1) + 6z-8/(z-1)10z/(z-1)(4z3 + 6)/(z7(z-1))10u[n-13]7. The input to a filter is x[n] = d[n] + 0.4d[n-1]. The output from the filter is y[n] = sin(np/2). The transfer function of the filter isH(z) = z2/(z3 + 0.4z2 + z + 0.4)H(z) = z2/(z(z + 1))H(z) = (z + 0.4)/(z2 + 1)H(z) = z/(z2 + 1)8. The transfer function of a filter is H(z) = (z2 - 0.2z + 0.3)/z2. Its difference equation isy[n] = y[n+2] + x[n+2] - 0.2x[n+1] + 0.3x[n]y[n] = x[n] - 0.2x[n-1] + 0.3x[n-2]y[n+2] = x[n+2] - 0.2x[n+1] - 0.3x[n] y[n] = d[n] - 0.2d[n-1] + d[n-2]9. The difference equation of a filter is y[n] = 0.7y[n-2] + x[n] - 0.3x[n-1]. The transfer function of the filter is H(z) = (1 + 0.7z-2)/(1 - 0.3z-1)H(z) = 0.7z-2 + 1 - 0.3z-1H(z) = (1 - 0.3z-1)/(1 - 0.7z-2)H(z) = (1 - 0.7z-2)/(1 - 0.3z-1)10. The impulse response for a filter is h[n] = 0.5d[n] - 0.4d[n-1] +0.25d[n-2]. The transfer function is H(z) = 1 - 0.4z-1 + 0.25z-2H(z) = z2 - 0.4z + 0.25H(z) = z-2 - 0.4z-1 + 0.25none of the above11. The transfer function for a filter is H(z) = 1/(1 + 0.4z-1). The impulse response isy[n] = -0.4y[n-1] + x[n]y[n] = 0.4y[n-1] + x[n]h[n] = d[n] + 0.4d[n-1].h[n] = (-0.4)n u[n]12. The transfer functions for two filters are H1 = 1/(1 + 0.2z-1) and H2 = 1/(1 - 0.8z-1). When the two filters are connected in cascade, the overall transfer function isH(z) = (1 + 0.2z-1)/(1 - 0.8z-1)H(z) = 1/(1 - 0.6z-1 - 0.16z-2)H(z) = (2 - 0.6z-1)/(1 - 0.6z-1 -0.16z-2)none of the above13. The transfer function of a filter is H(z) = 5z/(z-1)2. The impulse response for the filter is5(u[n])25sin(np/2)u[n]5nu[n]5(u[n] - u[n-1])14. The z transform of x[n] is X(z) = z3/(z3 + 1). The signal x[n] is1/(1 + z-3)(u[n])3n3u[n]1 - z-3 + z-6 - z-9 + ...15. The z transform of y[n] is Y(z) = 0.5/((z - 0.2)(z-1)). The signal y[n] is y[n] = 0.5(0.2)n-1u[n-1] - 0.5u[n-1] y[n] = 0.625(1-(0.2)n-1)u[n-1]y[n] = -0.625(0.2)n u[n] + 0.625u[n] y[n] = 1.25(0.2)n-1u[n-1] -1.25u[n-1]16. The poles and zeros of H(z) = (1 + 0.2z-1)/(1 + 0.4z-1 + 0.1z-2) are poles: -0.2 + j0.245, -0.2 - j0.245; zeros: 0, -0.2poles: -0.574, 0.174; zeros: -0.2 poles: -0.4, -0.1, zeros: -0.2 poles: -0.4 + j0.374, -0.4 - j0.374; zeros: -0.217.

The steady state value of the step response of y[n] + 0.3y[n-1] - 0.9y[n-2] =x[n] + x[n-1] is151019. The closer the poles of a stable filter are to the unit circlethe shorter the setttling timethe longer the settling timethe larger the steady state output the smaller the steady state output20.
