Let the random process X(t) be defined as X(t) = A + Bt, where A and B are independent random variables each uniformly distributed in [-1, 1]. a) Find the mean of X(t). b) Find Rx(t1, t2) c) Is X(t) wide-sense stationary?
A number stored in IEEE single precision floating point format has S=0, E=0111 1101, and F=0.1000 0000 0000 0000 0000 000. What is this number in decimal
The 24-bit data field of a packet is given by 0xBC603F. The packet contains a CRC with the generator polynomial given by X 3+X+1 a) Find the CRC checksum. Provide the complete code-word including the checksum in hex.
A -3.4 nC charge is on the x-axis at x_1 = -8 cm and a 4.6 nC charge is on the x-axis at x_2 = 17 cm. At what point or points on the y-axis is the electric potential zero
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
Define X and Y to be two discrete random variables whose joint probability mass function is given as follows: P(X = m, Y = n) = e^7*4^m*3^n?m / m!(n m)! , for m = 0, 1, . . . , n and n = 0, 1, 2, . . . , while P(X = m, Y = n) = 0
silicon is doped so that 1 in 10000 Si atoms is replaced by phosphorous atoms. A) Knowing that only 30% of the phosphorous atoms donate electrons at room temperature (30% ionization) , determine the effective doping level and electron concentratio..
Given the DSP system, where the sampling rate of 4000 Hz is used, the anti-aliasing filter is the Butterworth filter with a cut-off frequency of 200 Hz, and the percentage of aliasing level at the cut- off frequency is required to be less than 10%
Draw the per-phase impedance diagram of the power system and Draw the impedance diagram in per-unit system
A 30-km, 34.5-kV, 60-Hz three-phase line has a positive-sequence series impedance z = 0.19 + j0.34 ?/km. The load at the receiving end absorbs 10 MVA at 33 kV. Assuming a short line, calculate: (a) ABCD parameters,
The One river Hydroelectric Project generated power for BPA along the Two River from the early 1800s until 1900, when it was decommissioned due to environmental issues. The maximum flow rate through the system was 25 m3/s, and the hydraulic head w..
What do they mean by these two statements. For example, are they asking us to keep Voltage or Current constant in either statement and vary the Resistance finding the unknown Voltage or Current or what
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
