Imagine that you are the president of a small high-technology fi rm. Your company has grown over the last few years to the point where you feel that it is important that your employees have some guidelines regarding ethics. Define the type of company you are running, then develop an appropriate code of ethics. As in Question 2.5, start by deciding what type of code is appropriate for your company. Then, list specific points that are important-for example, relationships with vendors, treatment of fellow employees, etc. Finally, write a code that incorporates these features. In developing your code of ethics, you should think about the difference between business policies and ethical concerns. For example, business policies might be specific about what time workers should arrive each day and how many hours they should work; a code of ethics would focus more on integrity in following the business rules of a company.
determine the current through the capacitor, i_c(t) for time t greater than or equal to zero if the following statements apply. 1. Vc(t=0) = 5V 2. The switch is closed from t = - infinity to t = 0.2 seconds, when it opens.
Assuming the material is GaAs, calculate the Quasi-Fermi levels if the injected carrier concentration is 2x1018 cm-3.You can use the effective mass approximation and consider only the heavy hole in the valence band.
Show that H(s) is invertible with an LTI inverse that is causal and stable (meaning, we can implement the inverse system) if and only if all poles and zeros of H(s) are strictly in the left half plane. We call such an H(s) minimum phase.
We wish to measure the signal using a digitizer having a distributed cable capacitance of 350 pF plus a lumped input capacitance of 50 pF. Can this signal node be measured directly, or will a buffer amplifier be needed on the DIB?
1. How would you bias a BJT in a common emitter amplifier in order to minimize the Miller feedback capacitance 2. Explain how it is possible to identify the different current transport mechanisms.
Determine the load current of second synchronous generator and power factor of each machine, when excitation of first synchronous generator is decreased so that load current reduces to 100 A.
This capacitor is fully charged from a 120 V d.c. supply. Calculate the time taken, after disconnection from the supply, for the capacitor to become fully discharged.
In particular, find the maximum distance where the system performs reliable communication.
Energy is being created as time passes. We have more energy in the universe now than when time began.
The discrete-time signal x[n] is actually the result of sampling a periodic continuous signal x(t). The signal x[n] is 1 from -12 to +12, zero from n = 13 to 87 and then it repeats. What is the positive frequency (in hz) of the Null Bandwidth
Assume that C is completely discharged with S1 in the position shown. If S1 is moved to the top position, how much is the resistor voltage at the following time intervals?
Frequency multiplers are used at the transmitter to bring up the frequency level to the transmitter level frequency. Why don't we use the crystal oscillator to generate the transmitter level frequency
