A binary PAM communication system is used to transmit data over an A WGN channel. The prior probabilities for the bits are P (am= 1) = 1/3 and P (am = - 1) = 2/3.
1. Determine the optimum threshold at the detector.
2. Determine the average probability of error.
Discuss some of the major problems that cause leaky duct systems in older homes.
1-State the Difference between capacitance and inductance 2- List four types of electrical source with brief description 3-What are the differences between Thevenin's equivalent circuit and Norton's equivalent circuit 4- Assume that a sinusoidal volt..
The general belief is that the system exhibits a sharp phase transition from free flowing to fully jammed, as a function of initial density of cars. The existence of this sharp transition has been cited in the scientific literature several hundred..
A certain cyclotron that has a magnetic field whose magnitude is 1.8 T is designed to accelerate protons to a kinetic energy of 25 Mev. (a) What is the cyclotron frequency for this cyclotron (b) What must the minimum radius of the magnet be to ach..
By use of the Nyquist criterion, determine whether the closed-loop systems having the following open-loops transfer functions are stable or not. If not, how many closed-loop poles lie in the right half s-plane.
A 75 kW, 440 V, 3-phase, 6-pole, 50 Hz, wound-rotor induction motor has a full- load slip of 0.04 and the slip at maximum torque of 0.2 when operating at rated voltage and frequency with rotor winding short-circuited at the slip-rings. As sume the..
What is the common-mode voltage gain of Fig. 15-37? If a common-mode voltage of 20 μV exists on both bases, what is the common-mode output voltage?
For the circuit below using Theveins theorem, determine: The value of R to provide maximum power to the load. The maximum power transferred in the load
Determine the nodal displacements and axial stress distribution using (a) two equal-length elements and (b) four equal-length elements.
Determine the tap weight coefficients of a three-tap zero-forcing equalizer if the ISI spans three symbols and is characterized by the values x (0) = 1, x ( -1) = 0.3, and x (1) = 0.2. Also, determine the residual ISI at the output of the equalize..
A random variable X has a variance of 9 and a statistically independent random variable Y has a variance of 25. Their sum is another random variable Z=X+Y. Without assuming that either random variable has a zero mean
What is the average profit of firms that are producing? (Hint: Firms will produce as long as the price equals or exceeds unit production costs.)
