Part-B
• What is an embedded system? Example of Embedded system?
• Look at the following image and answer the questions below:
a) What is the full form of the following hardware?
b) What does it do to your device?
• Try to identify the image and answer the following questions:
This is a picture of a digital temperature scale. One can fit it into a room to check the
temperature but it can function without the help of electricity in a way.
(a) The following is a part of which embedded system?
(b) Do you think it has some characteristics related to the other kinds of embedded system?
Give one reason for your answer.
Level the Following box for Embedded System Workflow:
• Try to identify the image and answer the following questions:
The following is an example of Network system which is very popular now a days. It takes
user’s instruction or users can interfere through its system. Commonly it is also known as the
remote system.
(a) For the above system convert the following decimal to binary: (37)10 = (?)2
(b) Draw the workflow diagram for the following embedded system.
(c) Jot down the features of the following embedded system.
• Read the following case and answer accordingly.
While talking about OR gate, Mr. Robin said that OR gate is something that can easily be
constructed via simulation as it follows straight forward logic compare to AND gate. He gave
an OR logic statement to the students and told them to build the simulation.
(i) Draw the table method (truth table) for an OR gate.
(ii) Mr. Robin told his students to put a NOT gate before input 2 and construct the OR
gate. Then given the following data: -
Input 1 = 0 & Input 2 =1
• MS. Lija asked his students to build a logical circuit using AND gate. She has given them
two input AND gate. She also provided them with a table to fill out for the probable out.
The table has been given below:
Input 1 Input 2 Output
1 0
1 1
0 0
(a) Complete the above table by proving the missing data.
• Write down a pseudocode of REPEAT……………………. UNTIL
• Write down a pseudocode of IF………. ELSE IF………. ELSE
• Write a pseudocode example of DO……………...WHILE
Practical Activity
1. Construct the following AND gate with below data:
(i) When Input 1 is ON but Input 2 is OFF:
(ii) When Input 1 is OFF and Input 2 is OFF:
2. From the following table construct the logic simulation.
Input 1 Input 2 Output
0 1 0
1 0 0
1 1 1
3. Converting Celsius to Fahrenheit: 370 C
[Note: The formula of Celsius to Fahrenheit is (F = 9/5* C +32)]
4. Write a code to solve the equation z = (x – y) * (x + y)
5. Write a Python program to calculate the area of a trapezoid. Area = ½ (a+b) h
6.Input the price of 1 banana. Calculate and print the price of one dozen banana.
[ 1 dozen = 12 units]
7. Input the time in hours. Calculate and print the time in minutes. [ 1 hr = 60 min]
8. Input the age of two students in g1 and g2. Calculate and print their average age.
[Average = (g1 + g2)/2]
9. Input the distance travelled by a car in 4 hours. Calculate and print its speed.
[Speed = distance/time]
10. Input the length and breadth of a rectangular park. Calculate and print its
perimeter.

the cake in W. Calculate and print how much will each friend get.
[F = W/5]
12. "Subarna Express" had N number of coaches where the capacity of each coach was
80 passengers. Input the number of coaches. Calculate and print the total number of
passengers travelling in a journey.
13. Accept the height and base of triangle and display its area.
[ Area = 0.5 x height x base]
14. Input a number in N. Divide it by 10 and store the remainder in R.
Print the result. [Use operator %]
