Consider the development of a "through-beam" photoelectric sensor. A through-beam photoelectric sensor consists of a transmitting light source and a photo receiver. The transmitter and the receiver are lined up. When the beam is not broken, light from the transmitter hits the receiver and turns on the output transistor from the receiver. Their purpose is to detect objects as the objects break the beam. What are the operational parameters that must be determined before starting to design a through-beam photoelectric sensor?
Determine the Laplace transform of the above signals (use properties of the Laplace transform) including the corresponding region of convergence.
The reliability of a certain automatic cutoff device is assumed 11/12. What is the reliability of a system consisting of 4 such devices so arranged
Compute the homogeneous solution yh(t). Compute the particular solution yp(t).
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
Create a program using AsmIDE, which utilizes the Fox 11 68HC11 microcontroller board: Speech timer where max time is 5 minutes Use the switches for:
Compare the frequency response magnitudes for each of the responses above (will need to plot on a logarithmic scale). Comment on the observations noting things such as if the signals are resolvable, the size of the side lobes, etc.
why sinusoidal wave is chosen for AC fundamentals rather than a simple curve such as square or triangular wave?
what is transmission velocity and how it is different from drit velocity. Drift velocity the actual (physical) velocity of electrons along the wire.
Which one of the following statements is correct?
What are the incremental savings that result from increasing the efficiency of a PV collector by 1% in terms of collector area and costs? Assume that the PV module represents about 50% of the total PV system cost.
draw a combinational logic circuit (using AND, OR, etc.) that implements the function. (Note: x is a multiple of 3 if x=i*3 for some integer i.)
