In a binary communication system over an additive white Gaussian noise channel, two messages represented by antipodal signals andare transmitted. The probabilities of the two messages arep and 1-p, respectively, where The energy content of the each message is denoted by , andthe noise power spectral density is What is the expression for thethreshold value such that for the optimal detector makes a decision in favor ?
The loop transfer function L(S) of a single-feedback-loop control system is given below. Sketch the Nyquist plot of L(jw) for w=0 to w=infinity, Determine the stability of the closed-loop system.
Three single-phase transformers are connected in a wye/delta configuration. Each single-phase transformer has an identical number of turns in the primary and secondary windings.
What is the largest binary number that can be repressed with 14 bits. What are the equivalent decimal and hexadecimal numbers.
The steady-state electron distribution in silicon can be approximated by a linear function of x. The maximum electron concentration occurs at x = 0 and is n(0) = 2.0 x 1016cm-3. At x = 0.012cm, the electron concentration is 5.0 x 1015cm-3.
Sometimes the partial fraction expansion is not neede in finding the inverse Z-transform -instead the properties of the transform can be used. Consider the function F(z)= (z+1)/z^2*(z-1)
A. find the sixtieth percentile B. Find the seventy fifth percentile C. Determine the number of data points that fall between the sixieth and seventy fifth percentiles you found in parts A. and B.
Two points with the coordinates P(2, 5, -1) and Q (3, 0, 4) exists in space. Find the vector form of PQ, the lenght of vector PQ, and the unit vector form of PQ
A controlled three-phase six-pulse AC/DC converter is supplied with 60 Hz voltage of the line-to-ground RMS value U = 240 V with the output current ideally filtered by an inductor. The maximum DC power of the converter (Pd)max = 50 kW.
Identify the types of system-building methods used by Dorfman to build its wireless warehouse system.
How many turns of wire are required to produce a B-field whosemagnitude is greater than or equal to 10-3[T] inside anair-wound solenoid that is 2 [cm] long and carries a current of 100[mA].
Draw a state diagram for an FSM with an input "GCNT" and the outputs "X,Y,Z". The XYZ outputs generate a sequence called a Gray Code in which exactly one of the three outputs changes from 0 to 1 or from 1 to 0.
x[n]=cos(n*7pi/16)+cos(n*9*pi/16) a)Find the FS coefficients of x[n]. b)Obtain the DTFT of x[n] using the coefficients. c) Use Matlab, compute 25 seconds of the discrete-time signal x[n] using an appropiate sample period Ts.
