**Don't relay on my solution. Make changes before upload. I will not be responsible for your marks.**

Please carefully read the following instructions before attempting assignment.

It should be clear that your assignment would not get any credit if:
  • The assignment is submitted after the due date.
  • The submitted assignment does not open or file is corrupt.
  • Strict action will be taken if submitted solution is copied from any other student or from the internet.

You should consult the recommended books and lab manuals to clarify your concepts as handouts are not sufficient.

Your assignment solution must be in .zip format containing two files.

·         The first file will be an EWB file related to Activity 1.
·         The second file will be a word file (.doc) containing the solution of Activity 2.

Any other formats like scanned images, PDF, ppt and bmp etc will not be accepted.


No assignment will be accepted after due date via email in any case (whether it is the case of load shedding or internet malfunctioning etc.). Hence, refrain from uploading assignment in the last hour of deadline. It is recommended to upload solution file at least two days before its closing date.

If students find any mistake or confusion in assignment (Question statement), please consult with your instructor before the deadline. After the deadline, no queries will be entertained in this regard.

For any query, feel free to email at:

Question Statement:
In this assignment, you are required to design a circuit using “Electronic Work Bench”. The circuit needs to generate a clock pulse which remains ON for 30 secs and OFF for 10 sec for a complete 4 minutes.

For this assignment, you are required to go through the 555 Timer IC. The 555 IC datasheet is available in Downloads section of your course.

Students must go through the 555 Data Sheet and then by using the Electronic Work Bench application, perform the following activities.

Activity 1:

Draw a complete circuit diagram in Electronic Workbench to generate the above given Clock Pulse.

Activity 2:
You are required to calculate the following values for resistors & capacitors to generate the specified timing cycles.

555 Mono-Stable Timer

555 A-Stable Timer
