Design an elevator controller for a simple two-floor elevator. On the 1st floor, there is only an up button, and on the 2nd floor, there is only a down button. Within the elevator, there are two buttons: door open and door close. There are sensors that detect the status of door and location of the elevator.(a) Draw a block diagram with all the necessary input and output. State all your assumptions.(b) Draw the state transition diagram using either Moore or Mealy style, and explain the meaning of each state.
I)Design a circuit that gives you the following relation between input and output Vout = 2.17Vin + 5 Here are the constraints you need to work with: 1) Only one power supply that gives ±12V is available 2) Available op-amps run on ±12V
Consider a coffee counter with a single server at which tired students arrive according to a Poisson process. Let the mean arrival rate be two students per ten minutes and assume the serving time is exponentially distributed with an average of 180..
Calculate in polar form the sequence components of unbalanced lineto-neutral voltages and calculate in polar form the phase currents corresponding to the sequence components
Discuss the sequence of actions that occur in the operation of the control system for a traffic light, that includes sensors in the roadbed. Indicate which actions are time-driven and which actions are event-driven
Suppose that the type of key in a hashing application you are implementing is String. Design, implement, and test a hash function that converts a key to a hash value. Assume that the size of the hash table is a prime number.
1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current
Calculate the S/N ratio for a receiver output of 4 V signal and 0.48 V noise both as a ratio and in decibel form. (69.44, 18.42dB)
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
