2. The PSD is the Fourier transform of the auto-correlation function. ( The power can be calculated from a random signal over a given band of frequencies as follows: 1. Total Power in x(t): 2. Power in x(t) in range f1 - f2: 1The signal has to be stationary, which means that us statistics do not change as a function …

That function shows a relationship between power and sample size. For each level of sample size, there is a corresponding sample size. For example, if n=20, the corresponding power level would be about 0.97, or, if the power level is 0.95, the corresponding sample size would be …

The function is not a power function because the power is not constant. In fact, is an exponential function. d. Since. we see that can be written in the form where and , so s is a power function. As is the case with linear functions and exponential functions, given two points on the graph of a power function, we can find the function’s formula.

For the power function, begin with and take the natural log of both sides: ln y = ln A + p ln x. Note that the variables are y and x and A and p are constants. Because when a power function is used to begin with, the two variables ln t and ln y are related by a linear function.

Step 3: Since the objective function is Z = ax + by, draw a dotted line for the equation ax + by = k, where k is any constant. Sometimes it is convenient to take k as the LCM of a and b. Step 4: To maximise Z draw a line parallel to ax + by = k and farthest from the origin. This line should contain at least one point of the feasible region.

To calculate how long it will take for a train to come to rest when the locomotive power is cut off and the brakes are applied, and how far it will travel in this time, set . Since acceleration, f, is rate of change of velocity, a differential equation: describes the motion, and, once the initial speed is given, defines v as a function of time t.
