Passband Ripple: 0.1 dB ̇ Stopband: < 7 KHz and > 13 KHz ̇ Minimum Stopband Attenuation: 30 dB ̇ Sampling Frequency: 48 KHzThe filter turns out to be 10th order. The minimum number of bits required for stability (in asingle block) is determined using the m-file shown in Figure 1.Students simply vary the number of bits, B, and look at the resulting filter poles. The filterbecomes unstable when one or more filter poles has a magnitude greater than or equal to 1.0.For this particular example, the minimum number of bits required for filter stability is 9. The m-file in Figure 1 is also used to plot the filter frequency response (magnitude) for a specifiednumber of bits, B. Figure 2

Between Q and R scope, the following test case is not needed: − − −Q − −(P S) − − − R.There are two issues that are being checked by this test case; it checks that precedence is upheld 6when P and S hold at the same state, and it checks that the interval is built even when R occursin the last state of the computation. These two conditions are covered by test cases 2(a)(vi) and2(b)(iii) respectively as given in Table 3.3 Motivation The main contribution of this paper is to show how the aforementioned notions of patterns andscopes can be used in teaching black-box testing techniques. The motivation behind this use ofpatterns and scopes is twofold; 1) The characteristics of these patterns

We avoided thetemptation to create a really high tech teaching module, and instead we chose to try to create aningenious, yet fun way of exploring an engineering idea. This led us to the idea of creating alaminated arch. We offer this model up to others who are interested in K-12 outreach so thatthey too might be inspired to demonstrate our rich engineering heritage as we seek to inspirefuture generations of engineering students.

The same applies tointernational trade. How else can we be sure that a volt measured with a voltmeter produced inthe United States is the same quantity measured by a voltmeter produced in Germany (takinginto account the two instruments’ specifications, of course)?
