Answer #1

the figure shows the mod-12 counter and it's truth table

The clock here is negative edge triggered.

In this 4 T flip-flops are used.The number of the output states of a counter is called the modulus of the counter.the truth table will explains how it works.after 12 clock pulses the counter will reset .The NAND gate will make the counter reset.

Design a counter which counts in the sequence that has been assigned to you. Use D flip flops and NAND gates. Simulate your design using SimUaid. Submit the state table, D flip-flop input equations, and transition graph determined in Part 6. The D flip-flop equations can be derived using Karnaugh maps or using LogicAid by entering a state table with zero input variables. Sequence: 000,100,001,110,101,111,(repeat) 000,...

QUESTION 10 Question 10-12 are based on the following: In recent years more people have been working past the age of 65. In 2005, 27% of people aged 65–69 worked. A recent report from the Organization for Economic Co-operation and Development (OECD) claimed that the percentage working had increased (USA Today, November 16, 2012). The findings reported by the OECD were consistent with taking a sample of 600 people aged 65-69 and finding that 180 of them were working. Develop...

A large software company gives job applicants a test of programming ability and the mean for that test has been 160 in the past. Twenty-five job applicants are randomly selected from a large university and they produce a mean score of 183 and a standard deviation of 12. Use a 5% significance level and the critical-value method to test whether the mean score for students from this university is greater than 160. Assume the population is normally distributed. Correctly state...

A stock has a required return of 12%, the risk-free rate is 3%, and the market risk premium is 3%. What is the stock's beta? Round your answer to two decimal places. If the market risk premium increased to 10%, what would happen to the stock's required rate of return? Assume that the risk-free rate and the beta remain unchanged. Do not round intermediate calculations. Round your answer to two decimal places. If the stock's beta is equal to 1.0,...

Which of the following statements is CORRECT? Assume that the project being considered has normal cash flows, with one outflow followed by a series of inflows. a. The NPVs of relatively risky projects should be found using relatively low costs of capital. b. If a project's NPV is greater than zero, then its IRR must be less than the cost of capital. c. The higher the cost of capital used to calculate the NPV, the lower the calculated NPV will...
