The IC 74LS93 is a Modulus 2/8/16 Counter. The logic symbol is shown below. Q3Q2Q1Q0 are the outputs of the counter. If we want to use it as a modulus-16 counter, how should we connect the circuit？ 芯片74LS93是一个2/8/16进制计数器，逻辑符号如下图所示。Q3Q2Q1Q0是计数器的输出端。如果我们需要把它当做一个16进制计数器用，需如何连接电路？
A、Apply CP to CLKB 将时钟信号接入CLKB端
B、Apply CP to CLKA 将时钟信号接入CLKA端
C、Apply CP to CLKA, then connect CLKB to Q0 将时钟信号接入CLKA端，然后将Q0连接至CLKB端
D、Apply CP to CLKA and CLKB simultaneously 将时钟信号同时接入CLKA和CLKB端
For Barber, the logic of globalization trumps the logic of empire: the spread of Mc World under- mines imperial grand strategy. In most aspects of economic and political life, the United States depends heavily on other states. In an empire of fear, the United States attempts to order the world through force of arms. But this strategy is self-defeating: it creates hostile states bent on overturning the imperial order, not obedient junior partners.
Barber proposes instead a cosmopolitan order of universal law rooted in human community: "Lex humana works for global comity within the framework of universal rights and law, conferred by multilateral political, economic, and cultural cooperation—with only as much common military action as can be authorized by common legal authority; whether in the Congress, in multilateral treaties, or through the United Nations." Terrorist threats, Barber concludes, are best confronted with a strategy of "preventive democracy"—democratic states working together to strengthen and extend liberalism.
Barber's overly idealized vision of cosmopolitan global governance is less convincing, however, than his warnings about unilateral military rule. Indeed, he provides a useful cautionary note for liberal empire enthusiasts in two respects. First, the two objectives of liberal empire—upholding the rules of the international system and unilaterally employing military power against enemies of the American order—often conflict. Second, the threats posed by terrorism and weapons of mass destruction are not enough to legitimate America's liberal empire. During the Cold War, the United States articulated a vision of community and progress within a U. S. -lead free world, infusing the exercise of U.S. power with legitimacy. It is doubtful, however, that the war on terrorism, in which countries are either "with us or against us", has an appeal that can draw enough support to justify a U. S. -dominated order.
