what are the advantages of Linear versus buck-boost regulator.

Find the data hazards in the following code segment

   lw $t1,0($t1) 

   addi $t1,$t1,100

   or $t2,$t3,$t1

   add $a0,$a1,$t2

   ori $a0,$a0,42

   add $t5,$a0,$t2

Reorder the following code segment to remove the data hazards. Assume that data forwarding takes place:

   lw  $t0,24($a0)

   sub $t4,$t4,$t0

   sub $t8,$t8,$t3

   add $t6,$t6,$t5

   mul $t7,$t7,$t1

What is the CPI for the reordered sequence of instructions in the preceding problem?

In order to determine what level of PPE (Personal Protective Equipment) should be worn when working on, or observing, Energized Electrical Equipment, what type of study would need to be completed in order to provide labels for the equipment that would contain hazard boundaries, PPE required, and level of incident energy?

6 A 5 GHz signal is to be propagated in the dominant mode TE10 in a rectangular waveguide. If its group velocity is to be 90% of that of light. As engineer suggest i. What must be the dimensions of the waveguide (assume the standard waveguide)? ii. What impedance will the waveguide present to this signal if it is correctly matched?

Design a PLC ladder logic program to control a stop light. The program should have 3 outputs: RED, YELLOW, and GREEN. The ladder logic should illuminate green for 60 seconds, then yellow for 10 seconds, then red for 60 seconds. The system should also have two sensor inputs: THROUGH_TRAFFIC and CROSS_TRAFFIC which detect when there is through traffic and cross traffic present. If through traffic is detected, and no cross traffic is detected, the system should maintain a green light even after the green has remained lit for 60 seconds.

Consider a sequential circuit to control the washer:

The circuit receives 3 input signals: Clock, DoorOpen, and Start. It also maintains a state bit Wash.

If DoorOpen = 1, Wash should be set to 0.

Otherwise, if Start = 1, Wash should be set to 1 and if Start = 0, Wash should retain its value from previous cycle.

Make A truth table to compute the new value of Wash;

Make A circuit Diagram.

------------------------------------

How would the truth table look for this problem? I'm confused about how the state bit works with the table.

Here's my first attempt:

I don't know if this is right, let me know what is wrong with this.

Assume that you have a clock signal with frequency of 50 Hz, and you want to divide this signal into a frequency of 1 Hz signal. The counter chips you must use are synchronous decade (MOD 10) counter chips 74160 and synchronous MOD 16 counter chips 74161. Please use the back side of this paper to draw your circuit diagram with all the details.

You can use counter frequency division method to step down a higher frequency signal to a lower frequency signal. To divide a 50 Hz signal into a 1 Hz signal, you need to construct a counter with a total MOD 50 so that 50/50 = 1. To construct such a counter, you can use counter cascading method by cascading a MOD 10 counter such as 74160 with a MOD 5 counter so that the total MOD of the cascaded counter is 10x5 = 50. Since MOD 10 counter 74160 is a synchronous counter, you should truncate a synchronous counter such as a MOD 16 synchronous counter 74161 into a synchronous MOD 5 counter. You can use any additional logic gates in your counter truncation design.

The following given set of data shows a set of 15-minute kW demands for four customers over a 24-hour period. A 25kVA single-phase transformer serves all the customers.

(a) Find the maximum 15-minute demand for each customer and the average 15-minute demand for each customer

(b) Find the total kWh usage and the load factor for each customer.

(c) For the 25kVA transformer, compute the maximum 15-minute coincident demand, the maximum 15-minute non-coincident demand and the load diversity.
