Show the MATLAB code to compute and plot the frequency content of this temperature data, and then answer the following questions. a) What dominant peak do you see in the signal's frequency content (ignore the peak at zero frequency, which is just the sum of the temperature data)? b) What periodicity in time does this frequency peak correspond to? c) What sampling rate (samples per unit time) did you use in your analysis?

A conveyor motor has a N.O. START button (I:0/3) and a N.C. STOP button (I:0/4) to start and run the conveyor motor (O:0/4) when the START is pushed and released. When the conveyor is running bottles will pass a proximity sensor (I:0/2).  After 12 bottles have passed the sensor output O:0/5 must be turned ON (to have the bottles removed by a different machine) and the counter must be reset.  Sketch the program rungs to make this work.

Given the error of Figure, plot a graph of a proportional-integral controller output as a function of time. Let KP =4.7, KI = 3.1 3-1, and p(0) = 12 %, given ep(%) = 5.7 %

The LC-3 ISA has been augmented with the following push and pop instructions. Push Rn pushes the value in Register n onto the stack. Pop Rn removes a value from the stack and loads it into Rn. The following figure shows a snapshot of the eight registers of the LC-3 BEFORE and AFTER the following six stack operations are performed. Identify (a)-(d). BEFORE AFTER RO х0000 PUSH R5 RO х0000 R1 x1111 PUSH (a) R1 x5555 R2 x2222 РОP (b) R2 x3333 R3 x3333 PUSH (c) R3 x3333 R4 x4444 РОP R2 R4 x4444 R5 x5555 РОP (d) R5 x5555 R6 x6666 R6 x4444 R7 x7777 R7 x7777

Problem #4 Implement the function F = A'B' + AC + A’C'D using ONLY one multiplexor (of any size). In order to receive credit, your answer must be correct AND use good style. This includes good documentation practices – your implementation should be easy to verify. Needlessly inefficient circuits will be marked down.

Please answer this question with as much details possible, so I can understand. This is for Electrical Engineering.
