ECET 345 Inspiring Minds/newtonhelp.com ECET 345 Week 1 Lab Signal Observation And Recreation (100 Score) For more course tutorials visit www.newtonhelp.com Objective: Using a Tower system and supplied HCS12-based program, experimentally observe the closest equivalent of four key signals (impulse, sinusoidal, exponential, and square wave) on the oscilloscope and then create them in MATLAB. Equipment list: • Tower System with ADCDAC board • Oscilloscope • Three BNC to alligator • One PC running CodeWarrior 5.9

A shiny metal disk with a dark spot on it, as shown in figure below, is rotating clockwise at 100 revolutions/second in a dark room. A human observer uses a strobe that flashes 99 times/second to observe the spot on the metal disk (a strobe is a flashing light whose rate of flashing can be varied). The spot appears to the human observer as if it is rotating slowly 2. (a) A system samples a sinusoid of frequency 480 Hz at a rate of 100 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.

ECET 345 Inspiring Minds/newtonhelp.com ECET 345 Week 4 Lab Experimental Observation Of Aliasing (100 Score) For more course tutorials visit www.newtonhelp.com ECET 345 Week 4 Lab Objective of the lab experiment: The objective of this experiment is to observe the effect of aliasing in a discrete sampling system and to measure how aliasing alters the frequency of an input signal that is beyond the Nyquist limit. This lab can also be used to quantitatively and qualitatively observe the effect of an antialiasing filter, even though we do not do so in this exercise.

  9. ECET 345 Inspiring Minds/newtonhelp.com ECET 345 Week 5 Ilab Convolution Of Signals Solution (100 Score) For more course tutorials visit www.newtonhelp.com Objective of the lab experiment: The objective of this experiment is to demonstrate how the convolution is used to process signals entering a system. 1. Convolution in the time domain is equivalent to what mathematical operation in the frequency domain? 2. When we convolve the triangular 10 Hz input with the impulse response of the 50 Hz low-pass filter, why is it that the peaks of output become rounded and not a sharp point as in the input triangular function? 3. Why is it that we get no (or very little) output when we convolve the 60 Hz sinusoid with the impulse response of the filter? 4. When we apply the 10 Hz output, which is within the pass band of the filter, we see that we get nearly the same sinusoid in the output except for a time delay. How is the time delay a signal experiences as it passes through a system related to the phase characteristic of the system response?

Hint: Follow the method used in the lecture for Week 6. Also, when evaluating the numerical value of a trig function, keep in mind that the arguments of trig functions are always in radians and not in degrees. 2. Find the system transfer function of a causal LSI system whose impulse response is given by and express the result in positive powers of z. Hint: The transfer function is just the z-transform of impulse response. However, we must first convert the

Towards this end, we shall learn how to use Fourier transform to obtain Bode plots of systems from time domain data passing through the system. We shall also learn the equivalence of convolution operation in time domain with multiplication operation in frequency domain. (a) Application of Fourier transform to time domain signals
