Drawing a root locus and finding the dominant roots

Please see my attached questions. I actually only need no. 24 and 25. Solution Preview We can write this function as the ratio of two polynomials in , a numerator polynomial and a denominator polynomial , thus On examination we can equate In a negative feedback system the closed loop transfer function is given in […]

Fourier analysis using Excel

The supply current was sampled 1024 times over a very short time interval. The data so obtained is given in column B of the accompanying Excel worksheet (see attached). This worksheet has been set up to give a graph showing the spectral components of the data. Question 3 i) Obtain the Fourier Transform for the […]

plot continuous and discrete-time signals in Matlab

See attached file for full description: Activity 1: Consider the discrete-time signal: x[n] = sin(2*pi*Mn/N), and assume N = 12. For M = 4, 5, and 10, plot x[n] on the interval 0 =< 0 < = 2n – 1. Use stem in Matlab to create your plots, and be sure to approximately label your […]

Break Even Stripping Ratio (BESR)

Given an underground total mining cost of $8.85 per tonne, surface mining costs of $2.95 per tonne of ore, and surface mining stripping costs of $1.75 per tonne of waste, calculate the break even stripping ratio (with zero profit) between surface and underground mining. Break Even Stripping Ratio (BESR) = (cost of underground mining per […]
