a six sigma black belt found that in a random sample of 140 printed circuit boards, 18 are defective. At the 5% level of significance, test that the percentage of defective boards is 10% against the
Allocate this block to 3 different customers. Customer 1 requires a block at least 10 addresses, customer 2 requires 254 addresses, customer 3 requires 2 addresses. Give a possible allocation of the
How would you determine whether a given function, f(t), had finite or infinite energy. Give an example of a function with finite energy and one with infinite energy.
f(t) = A[u(t) + u(-t/2-5)-1], where u(t) is the unit step function. Is the energy of this signal finite? Why or why not. If it exists, find the energy of this si
An EKG signal is contaminated by 60-Hz noise. Design a bandstop filter to remove this noise while limiting distortion of the EKG signal. Sketch the magnitude and phase response.
We are required to create a digital clock for the upcoming project. The class has been very disorgainzed and hard to follow, thus I've had a hard time keeping up with what's actually going on and do
