## 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 […]

## even and odd signals

Signal Processing & Wavelength. Problems # 6-7. See attached file for full problem description. 6. For each of the signals given, determine mathematically if the signal is even, odd, or neither. Sketch the waveforms to verify your results. For signals that are neither, find the even or odd parts of the signal. a) x(t) = […]

## 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 […]

## Erlang B

A single GSM service provider supports 10 digital speech channels. Assume the probability of blocking is 1.0%. From the Erlang B chart find the traffic intensity and determine how many 3 minute calls this represents: a) 20 calls b) 100 calls c) 50 calls d) 240 calls Solution Preview From the Erlang B table, the […]
