1) Assume that we are given the continuous-time signal xa (t) = xa1 (t) + xa2 (t) + xa3 (t), where, xa1 (t) = 2 + cos3 (2pf1 t + p 3 ) + 2 cos(2pf2 t), xa2 (t) = 2 cos(2pf3 t)
Can add vectors using the parallelogram rule Can multiply a vector by a scalar - result is a parallel vector • length is scaled
Q. Three waveforms seen on an oscilloscope are shown in Figure. If the horizontal scale is set to 50 ms per division (500 ms for the entire screen width), and the vertical scale is
Q. Use a 4-to-1multiplexer to simulate the following: (a) NAND logic function. (b) EXCLUSIVE-OR logic function. (c) Σ m (1, 2, 4).
principle of resistive feedback circuit change when the square wave and triangular pulse frequencies, the amplitude of the triangle wave
DI Disable Interrupts Instruction The interrupt enable flip flop is reset and all the interrupts of 8085 microprocessors except TRAP are disabled . the instruction form
Multiprocessing - Many Processors Many users Many Programs Multiprocessing or also called distributed processing system provides solution to problems of above timesharing
Q. For a JKFFwith JK = 11, the output changes on every clock pulse. The change will be coincident with the clock pulse trailing edge and the flip-flop is said to toggle, when T = 1
(a) Give three different ways how electro-magnetic interference can be reduced in twisted pairs based transmission. (b) Noise are unwanted signals affecting transmission. Lis
