Select two different kinds of qualitative variables and two different kinds of quantitative variables.
Is it possible to assign 3 data bits to each point of the signal constellation such that the nearest points differ in only 1 bit position?
Determine the autocorrelation function of the sequence {In}.Determine the power density spectrum of u(t).
Assume that it is desirable to have a zero in the power spectrum at f = 1/T . To this end, we use a precoding scheme by introducing bn = an + kan-1.
Determine the autocorrelation function of Z(t) when X(t) and Y (t) are uncorrelated and have zero means.
Determine the power spectral density and the autocorrelation function of Y(t) = X2(t).
Determine the autocorrelation function of Y (t) in terms of the autocorrelation function of X(t).
Determine the mean, the autocorrelation sequence, and the power density spectrum of the output of a system .
Determine the conditions under which the power density spectrum of X(n) is equal to the power density spectrum of X(t).
Let X(t) denote a (real, zero-mean, WSS) band pass process with autocorrelation function RX(t ) and power spectral density SX( f ).
Suppose that X is a Gaussian random variable with zero mean and unit variance.
As a generalization of the two-dimensional transformation of the Gaussian random variables considered .
Show that if X is a Gaussian vector, the random vector Y = AX, where the invertible matrix A represents a linear transformation, is also a Gaussian vector.
Show that if both A and n go to infinity such that n A = ?, where ? > 0 is a constant, the density function of Yn tends to an exponential density function.
A random experiment consists of drawing a ball from an urn that contains 4 red balls numbered 1, 2, 3, 4 and three black balls numbered 1, 2, 3.
The random variables Xi, i = 1, 2, ..., n, have joint PDF p(x1, x2,..., xn).
If the channel output is A, what is the best decision on channel input that minimizes the error probability?
Let demand, D, follows N(1000, 50^2) bundles of products yearly. The delivery lead lime is 3 weeks. Each order costs $60 regardless of the order quantity
Lenovo uses the ZX-81 chip in some of its laptop computers. The prices for the chip during the last 4 months were as follows:
Leah's has determined that the current process has an underlying p value of 0.01, meaning that, on average, 1 out of 100 rattles is currently judged
Research area which is of interest to you (e.g., a topic you may want to do your dissertation on), and pick a hypothesis you may want to test.
On a third column, calculate Index, taking into assumption that for year 1984 it is 100. Format it to 1 decimal place
Large-scale integrated (LSI) circuit chips are made in one department of an electronics firm.
Last fall, a sample of n = 36 freshpeople was selected to participate in a new 4-hour training program designed to improve study skills.
Karen Villagomez, president of Wright Industries, is considering whether to build a manufacturing plant in the Ozarks
