Frequency Divider: Use a count-for-50M counter and some glue logics to construct a 1 Hz clock frequency. Construct a frequency divider of this kind. 2.1 Write the specification of the frequency divider. 2.2 Draw the block diagram of the frequency divider.

The neutral point of 25MVA, 11kW alternator is grounded through a resistance of 5Ω, the relay is set of operate when there is an out of balance current of 2A. The CTs used have a ratio of 1000/5. Calculate (neglect resistance of alternator):
i. The percentage of stator winding protected against earth fault.
ii. The minimum value of earthing resistance to protect 95% of the winding.

A 4-quadrant is known as a versatile singe-phase converter that can generate any periodic output voltage of almost any frequency, phase angle, amplitude and wave shape. Explain how this can be achieved?

Can you explain the difference between the following two methods:

1)zero padding

2)periodic extension

when computing DFT of finite extend signals.

Create a program that stores the information of up to 50 containers loaded on ship. The program should contain a menu to do the following:

A or a     to add a container.

R or r      to retrieve the information of one container.

T or t      to retrieve the information of all containers.

W or w   to retrieve the total weight of the loaded containers.

X or x      to exit the program

Ask the user for the number of containers to be loaded, create an array of floats with five rows and a number of columns equal to the number of containers provided by the user.

Option A: for this option check if the array has an empty column to enter the information for a container, if not, output a message indicating that array is full. If array is not full, ask the user for the ID number, length in meters, width in meter, height in meters, and weight in Kg of the container and store them in the array.

Option R: Ask the user for the desired ID number to be searched. If found, output the ID number, length in meters, width in meter, height in meters, weight in Kg, and volume in cubic meters of the container each on a line. If not found, display a message to that effect.

Option T: retrieve the info for all containers in the array with a dotted line separating one another. The info retrieved and calculated should be the same as the above step.

Option W: display the total weight of all the containers in the array.

Option X: Exit the program.

how does lighting affect worker productivity

. What does each line of the following code do?

fsrPin = ‘A4’; ledPin = ‘D4’;

anArduinoObj = arduino();

forceVoltage = readVoltage(anArduinoObj, fsrPin);

if forceVoltage > 4.0

writeDigitalPin(anArduinoObj, ledPin, 1);

end

Based on the Adafruit pages related to their round FSR sensor, what is the required force to read a voltage greater than 4V?

XNOR (is it 2?)

NAND

With an Arduino Uno:

Using 2 external buttons b0 and b1 to represent ‘0’ and ‘1’, design a sequence detector to detect a pattern “1101”. An LED lights up once, when the sequence “1101” occurs.
