Design and simulate a regulated power supply using a bridge
rectifier, capacitors, and zener diode ( no integrated circuit).
The source voltage is 110 plus or minus 10 Vrms, 60 Hz frequency.
The output voltage is as follows (plus or minus 5%) : 4.5 V and 12
V
It has to be done on a breadboard. The rating of the adapter
will be 12W and 5% regulation. To protect the circuit include a
surge protection and fuse in the circuit...
What factors discourage the use of redundant members or novel materials in bridge design? What role should inspections/maintenance play in structural design? What is a strain gauge? How does it work? How can it be used to prevent structural failure?
2. Create a new NetBeans project called PS1Gradebook. Your
program will simulate the design of a student gradebook using a
two-dimensional array. It should allow the user to enter the number
of students and the number of assignments they wish to enter grades
for. This input should be used in defining the two-dimensional
array for your program. For example, if I say I want to enter
grades for 4 students and 5 assignments, your program should define
a 4 X...
Design a 3-bit 2’s complement adder/subtractor with
overflow flag detection
Design and simulate a structural model (not
behavioral) of a 3-bit Adder/Subtractor). Use the 3-bit carry
propagate adder of the project as a module for your
adder/subtractor. The inputs A and
B should be positive binary numbers where vector
B must be converted to a negative 2's complement
when a subtraction operation is configured. When m=0 it should
perform and addition (A+B) and if m=1 it should
perform a subtraction...

Design a survey questionnaire that gather information on who, when,
and how individuals use online shopping. Ask 20 questions that
provide quantity, frequency and reasons for their use, which will
help you analyze the impact of online commerce on transportation
and urban development.
