How can firms assess the business value of information systems projects?
• List and describe the major costs and benefits of information systems.
• Distinguish between tangible and intangible benefits.
• Explain how real options pricing models can help manages evaluate information technology investments.
1. The PowerPC 601 processor addresses a maximum of 2^(32) bytes of memory. What is the maximum number of 64-bit words that can be stored in this memory. 2. A certain IBM 970 processor has a system clock frequency of 1.2 GHz, what is the clock peri..
If the signal is connected to the input of an inverting op-amp circuit, what voltage gain is necessary so that the output of the amplifier produces a change of 2 V for every degree change in temperature
(a) Give the Boolean function Y . (b) Sketch a PDN directly from the expression for Y. Note that it requires 12 transistors in addition to those in the inverters (c) From inspection of the PDN circuit, reduce the number of transistors to 10
Implement the circuit with a block diagram decoder (you don'tneed to show the internal implementation of the decoder) and OR gates only. Implement the following Boolean function with a multiplexer.
What do you envision as the future of this device?
Show how the functions can be transformed into linear curves - Estimate the overall uncertainty for this system, using the maximum possible FSO in your computations. What would the uncertainty be if the hysteresis error were removed?
What is the bandwidth required so that the modulated signal contains atheist 90% of the power of the unmodulated carrier. A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.
Create a chart summarizing the details of the investment for both Bob and Lisa.
Discuss the steps required in calculating the collector-emitter voltage in a VDB circuit. Why does this circuit have a very stable Q point Discuss whether transistors being used as switching circuits should be biased in the active region.
The resistance is .4 ohm for each transmission wire connecting the motor source. If the motor was operating at 100% pf and eff and the cost of electrical power was $.10/kWh, how much can be saved each year if the motor was wired to the 240.
The motor runs at 570 rpm. Ignore the rotational losses and calculate the full load torque.
Fatigue life (in hundreds of hours) for a certain type of bearing has approximately a Weibull distribution with γ = 2 and θ =4.
