1. Is an SSS random process x(t) necessarily mean-ergodic? Explain.
2. If x(t) and y(t) are two zero-mean WSS random processes with Rxy(τ ) = 0 for all τ , is it always true that
Explain.
A load operating at 2300 V rms draws 28 A at a power factor of 0.812 lagging. Find (a) the peak current in amperes; (b) the instantaneous power at t=2.5 ms assuming an operating frequency of 60 hz; (c) the real power taken by the load.
Use Gauss's law to obtainexpressions for the electric field intensity E in both regions: r> a and r
A single phase cyclo converter with mid point configuration is used for obtaining an output frequency of 1/3 times the input frequeny.Turns ratio from primary to upper seconday is 1/1 and to lower secondary is 1/2.
A voltage source V = 119
The frequency is t = 300MHz. The medium is vacuum. Find the wave vector k and write the expression for the vector field phasor E at the point [0,sqrt (2)] bearing in mind that the field phasor at the origin is E(0,0,0) V/m.
Realize each of the following functions as a minimum two-level NAND-gate circuit and as a minimum two-level NOR-gate circuit. (a) F(A,B,C,D) = BD′ + B′CD + A′BC + A′BC′D + B′D′
An enhancement type nmos transistor with Vt = .7 V conducts iD= 100 micro A .. when V GS = V DS = 1.2 V . Find the value of i D for V GS = 1.5 V and V DS = 3V . caculate the value of the daain source resistance r DS for small V DS and V GS = 3.2 V
If four fires are independently reported in one day, find the probability that two are in family homes, one is in an apartment, and one is in another type of dwelling.
magnetic field, B, is constant, supplied either by a constant field current or by permanent magnets. The input voltage to the armature of the motor,Vin , connects to a circuit containing the armature impedance, R and L in series, and a dependent v..
Immediately after the explosion, the velocity of the 1200 kg upper stage is 5700 m/s in the same direction as before. What is the velocity (magnitude and direction) of the 2400 kg lower stage after the explosion
The equivalent circuit for a typical automotive battery charging system is a three-phase delta-connected source which represents thestator coils of the alternator. a) Sketch the load voltagevoltage vt(t) to scale vs time.
Design a bandpass filter using the frequency sampling method. Choose the order of the filter appropriately so that there is one sample in the transition band. Use optimum value for this sample.
