# EE263 HOMEWORK 9 SOLUTIONS

Find the gradient of the following functions. The signal w t is called the process noise, and the signal v t is the measurement noise. In other words, the network is used to collect information from the nodes and route it through the links to the special destination node. Without any further assumptions, you cannot determine x. You can think of H as a rational transfer function, with s the complex frequency variable. The positions of the cells are x1 , y1 , x2 , y2 ,. We have two types of cells: The spot measurements are not perfect as we assumed in part a ; they contain small noise and errors. Plot c, d, and w, and r. We will consider two different methods to choose x. There are K wires that connect pairs of the cells. To visualize the arrays use the matlab command imagesc , with matrix argument. These signals, which collectively are called the signal constellation, are known to both the transmitter and receiver. Plot the trajectory of the two vehicles in R2 using something similar to plot p1 1,:

You may assume that the norm of the least-squares approximate solution exceeds one, i. How long will it take to affect the other species populations? This problem concerns three proposed methods for estimating a signal, based on hoemwork measurement that is corrupted by a small noise and also by an interference, that need not be small.

## Rsa homework solutions

Links 4 and 5 enter this node, and link 6 leaves the node. The measurement error v is not known, but is assumed to be small. Note that the edges are oriented, i. Explain your method, and give your estimate for the emissions rates of the three sources.

AN ESSAY ON FISCAL FEDERALISM OATES 1999

You do not know solutioons parameter s, or the channel impulse response h 0. In this problem we explore a simple version of a tomography problem. Thus, you must choose the inputs up to time Mu homewrku 2.

We consider the phased-array antenna system shown below. Your solution which includes what you can say about A and B, as well as your justification must be short. Airlines are required to collect this data, called FOQA data, for every commercial flight. It is also called a Gauss-Markov slutions, which is a fancy name for a linear system driven by a noise.

After this processing, it is acted on by another channel, given by A.

The knowledge is given as a graph on the indices 1. Also give the transaction cost if all the shares were purchased in the first period, and the transaction cost if the purchases were evenly spread over the periods i.

If all coefficients i. A digital circuit consists of a set of n logic gates, interconnected by wires. Be sure to explain how you solve this problem, and to explain the matlab source code that solves it which you must submit. For this reason we call decoding matrices with this property solutlons.

So, for example, a sequence that contains would not be valid, because the sum of the first three consecutive symbols is 2.

The matrices A and B are given, and the goal is to find a matrix X that satisfies the equation, or to determine that no such matrix exists. There is no such thing as a nonlinear unbiased estimator. The data is given using cell arrays X and y. The graph is symmetric, so the edge i, j simply means that i and j are connected homewokr an edge.

Report the associated values of r the return hoework, and Rid the idiosyncratic risk. The components of the inputs might be, for example, the deflections of various control surfaces and the thrust of the engines; the output might be vertical acceleration. In that es263 you obtained the quadratic extrapolator by interpolating the last three samples; now you are obtaining it as the least squares fit to the last ten samples.

Identify any pairs of the methods that coincide i. If you need to make any assumptions about rank of some matrix, do so. For example, in the graph shown above, 1, 2, 3, 2 is a path of length 3. Pick the statement that is true, and justify it completely.
