------------------------------------------------- Part 1- Implement Asynchronous Counters Theory: 1. What makes a counter asynchronous? The counter is asynchronous because its clock is only applied to a single flip-flop. 2. What is the modulus or count range of the following counter? 16 cycles will count from 0-15 Planning: 3. What is the purpose of the ELVISmx Dig In instrument? display the output of the counter Test Procedure: 4. Record the observed values from Lab 5 Table 5-1

The maximum possible number of states (maximum modulus) of a counter is 2n. Where n is the number of flip-flops in the counter. TRUNCATED SEQUENCES: Counters can also be designed that have a number of states in their sequence

Timers and Counters Exercise 2.2 1. Define the following timer bits: timer enable, timer timing, and timer done. ANSWER: Timer enable bit: The enable bit is true when the rung input logic is true, and the enable bit is false when the rung input logic is false. When the EN bit is true the timer accumulator is incrementing at the rate set by the timer time base. Timer timing bit: indicates when timing action is occurring and can be used to control timed events in automation applications. Timer

Countertrade can be separated into five variants: 1. Barter 2. Counter purchase 3. Offset 4. Buyback or compensation 5. Switch trading Barter is simply the direct trading of goods and or services between two parties with not monetary exchange. It is normally used in one-off deals with trading partners that are not trustworthy or that lack any credit. Barter is the simplest and most restrictive type of countertrade. Counter purchase is a mutual buying agreement which involves one party agreeing

Cook’s paper first states that as a result of the recent September 11th, 2001 attacks pertaining to the Pentagon (Washington D.C) and the World Trade Center (New York City), the concept of just warfare - the moral and legal traditions of just war and its appropriate, yet effective response has vastly differed and have been challenged. Not only are they subjective to interstate war, but are also

maintain terrorism as a money making enterprise. The issue of terrorism financing is an important one. However, when these organizations come up with techniques to finance themselves, stopping them gets much tougher. Measures have been taken to counter these activities but clearly lack the effectiveness that is required making it all the more necessary to take decisive actions in stopping the menace caused by strongly financially supported terrorist
