Compute the first 10 samples of the step response for the nonrecursive difference equation:
y(n) = x(n) -0.5x[n-1]-0.7x[n-2]
Indentify which of the following filters are recursive and which are nonrecursive. For each filter, indentify the coefficient ak and bk-.
(a) y(n) = (x[n] + x[n-1]+[n-2]/3
(c) y[n] = 0.5y[n-1]+x[n]-0.4x[n-1]
At what temperature are the two carrier densities equal?
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
Determine whether the follow signals are period and for those that are find the fundamental period. F: x(t) = cos(t)u(t) G: x(t) = v(t) + v(-t) where v(t) = cos(t)u(t) I: x[n] = cos((1/5)(pi)(n)) * sin((1/3)(pi)(n))
A fluid flows through a turbine at the rate of 45 kg/min. Across the turbine the specific enthalpy drop of the fluid is 580 kj/kg and the turbine loses 2100 kj/min in the form of heat energy. Determine the power produced by the turbine.
What is the smallest number of samples that could be collected in order to know for sure whether or not the 1000Hz component is present? Assume you are using a Rectangular window.
How would you develop a looping program in MIPS that will take a series of decimal numbers and arrange them in ascending order from smallest to largest. The sequence of nine numbers are: 5, 3, 8, 9, 2, 4, 1, 7, 6, 3, 8
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
A single-loop negative feedback system has the loop transfer equation: L(s)=Gc(s)G(s)=K(s+2)^2 / (s(s^2+1)(s+8)) a. Sketch the root locus for 0 K infinity to indicate the significant features of the locus. b. Determine the range of the gain K for whi..
