1- for the linear system : Sak y(n-k) = S br x(n-r) , (series a are from k=0 to n ) & ( series b from r=0 to m)
a- find H(z)
b- does this equation uniquely specify the unit sample response of l.s.i system ?
c- choose, stable and casual system ,discuss regions of convergaince (ROC)
2- find the convolution of : x1(n)(1/2)n u(-n-1) , x2=(1/2)n u(n
3- find convolution of : x1(n)=[1 2 3 0] , x2(n)=[1 -1 1 1] , n=[0 1 2 3]
In US, electric wires are classified based on their gauge numbers. The larger the gauge number is, the smaller the diameter of the cross-section of the wire becomes. You are given four different types of wire with gauge numbers 1, 3, 7, and 8.
The energy (power) in Watts in an electrical circuit is described by P = VI, where V is volts and I is current
The unit impulse response of an LTIC systems is h(t) = (1- 2t)e^-2t * u(t) Find this system's (zero-state) response y(t) if the input x(t) is: 1) u(t) 2) e^-t u(t) 3) e^-2t u(t) 4) sin(3t) u(t)
A wire is stretched between two posts. Another wire is stretched between two posts that are twice as far apart. The tension in the wires is the same, and they have the same mass. A transverse wave travels on the shorter wire with a speed of 281 m/..
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
The memory unit, 2M x 32, is specified by the number of words times the number of bits per word. How many address lines and input-output data lines are needed And give the number of bytes stored in the memory.
Write the equation for the voltage across the capacitor for all time t > 0 (that is, after the switch opens at t = 0). Assume that the switch has been closed a long time before t = 0 to determine the initial condition on the capacitor.
A linear time-invariant continuous-time system responds to the following inputs with the corresponding outputs:Ifx(t) = u(t), then y(t) = 2(1- e^-t)u(t) and if x(t) = cost,then y(t) = 1.414 cos(t - pi/4).
A GAL is different from a PAL because A GAL has more inputs and outputs; A GAL is implemented with a different technology; A GAL can replace several different PAL's; A GAL can be reprogrammed and a PAL cannot
Design a sequential circuit which adds two to a binary number in the range 0000 - 1001. The input and output should be serial with the least significant bit first. Find a state table with a minimum number of states.
1- a port device may have multi-byte data input buffers and data output buffers. what are the advantages of these 2- what are the advantages of DAA(Data Access Arrangement) and McBSP ports in DSPs
The lifetime of a turtle is a continuous value uniformly distributed between 50 and 150 years. Let X and Y be the lifetimes of two randomly chosen turtles, and consider the following events: A = {X
