MCQ->A sequential multiplexer is connected as shown in figure. Each time the multiplexer receives the clock, it switches to the next channel from 6 to 1. If the input signals are : A = 10 cos 2p (4 x 103t) B = 15 cos 2p (5 x 103t) C = 20 cos 2p (6 x 103t) D = 10 cos 2p (10 x 103t) The minimum clock frequency should be __________ kHz. ....
MCQ->The area of a plot is to be determined using Simpson's rule. The following offsets were taken to a boundary from points along a chain line all measurements being in metres 12, 15, 22, 29, 36, 38, 31, 22, 17.There were taken at 100 m intervals. Consider the following steps in this regard. 1. 2. Sum of the odd ordinates = 22 + 36 + 1 = 89 3. Sum of the even ordinates = 15 + 29 + 38 + 22 = 104 4. 12 + 17 = 39 5. Area = 100 (19.5 + 89 + 104) 6. Area = (39 + 2 x 89 + 4 x 104) 7. Area 100 x 19.5 (104 - 89) The area of the plot can be determined by using the steps listed above :....
