Explain how to build a circuit for a light controlled by two switches using OR gates, AND gates, and inverters.
An ideal transformer is used for maximum power match of a 2880Ohm load to a source with a Thevenin Equivalent of 18 V and 20Ohms. (a) If the transformer primary has 140turns, how many turns are needed for the secondary
draw a digital design consisting of 2 input AND gates and three inverters, where an inverter is connected to each of the AND gates input and its output. For each of the four possible combinations inputs applied to the two primary inputs.
Describe the general guidelines for structuring data-entry fields. Can you think of any instances when it would be appropriate to violate these guidelines?

Design an FSM that recognizes an input sequence that has at least three 1's. More specifically, the FSM has one input, X, and one output, Y. Define the necessary number of states and what each state represents
Suppose the government cuts taxes. Using a supply and demand analysis of the capital market, explain what the impact of the tax cut will be on the equilibrium real interest rate at full employment.
What is the purpose of a high-pressure switch in a packaged air handler?
By now, you should have been up in the PLC lab getting familiar with the HMI and how to program it; how to define new screens, label them, and access them from the F# tabs below; and how to design Icons/Images from the Library that links HMI image..
Design a full-wave bridge rectifier to deliver 12DC with less than 0.1V ripples into a load drawing 100mA. Specify any components as well as the input AC voltage required. Assume 0.6V diode drops.
For a first order low pass filter, with a cut-off of 2 kHz, how many decades and octaves would the frequency be if the attenuation was -58 dB. What would the frequency be at that attenuation.
