What is excitation as applied to electrical machines?

What is an interrupt vector table. How do I create an interrupt vector table in Arm Architecture . Please include as much information as you can, including pictures, examples etc. Thank you very much.

Which has the greatest NPV assuming a 25 year planning horizon and MARR = 12%?

Install a $20,000 solar system that will last 25 years, and generate 38,000 kWh/year at $0.10/kWh.
Install a $25,000 Ground-Source Heat pump that will last 50 years and save $3,500/year.
Both options has equal NPV

Question 6: Recommend/ Explain a program that takes the information of 40 students in following order
Name:

Father Name:

Enrollment number:

Date of birth:

After taking the information of the students, it then displays the entered information.

what are the two basic types of control circuits

Design a sequential traffic light controller for the intersection of street A and street B. Each street has traffic sensors which detect the presence of vehicles approaching or stopped at intersection.

Sa=1 means a vehicle is approaching on street A.

Sb=1 means a vehicle is approaching on street B.

There are 3 outputs of each streets RedA, YellowA and GreenA, RedB, YellowB, and GreenB.

Condition: “StreetA” is a main street and has a green light for at least 50s, after 50s if there is a car approaches on “StreetB”, the light changed to yellow then red and “StreetB” has green light for 50s.

At the end of 50s, the light change back unless there is a car on “StreetB” and none on “StreetA”

Present the code and develop a waveform using the Quartus Prime 19.1 Lite edition.

Please describe the major difference between the Model based system and a Smith Predictor (i.e. what was required additionally, by one of the two systems).

consider a system with the impulse response

h(t) = e −t [u(t) − u(t − 2)]. (It's exponential function)

Let the input signal x(t) be x(t) = 1 if 0 ≤ t < 1, x(t) = −1 if 1 ≤ t < 2, x(t) = 0 otherwise.

(a) Determine the system output y(t).

(b) (20) Plot y(t) using a computer and specify the maximum and minimum.

Problem 3: A single phase 60 Hz two-winding power transformer is rated at 2400V/240V and 100 kVA with
Zeq = 0.5 + j0.8 Ohm. If an autotransformer is built from this conventional transformer to supply a load at
2640V with supply voltage 2400V. Draw the autotransformer and calculate Zeq, the voltage, current and
apparent power rating of the auto transformer. Also calculate the apparent power rating advantage of
autotransformer over conventional transformer.

The complex power absorbed by a load is S= 850∠-25⁰. This means the load is ________ and pf is___________(a) Inductive , lagging(b) Inductive, leading(c) Capacitive, lagging(d) Capacitive, leading
