a) Using a 555 timer IC, generate a square wave with a total time-period of 3 ms and a duty cycle of 30%. Draw the clear circuit diagram required for the generation of the waveform and calculate the values of resistors and capacitors used. (7 Marks) b) Simulate the circuit designed in part (a) using appropriate simulation tools and verify the output. The answer should include details such as aim, brief procedure, screenshot of resultant waveforms and calculations of the practical time-period obtained and your reflections on the results obtained. (9 Marks) c) A 555-monostable multivibrator is designed with pulse width is 5 ms. If the output of the circuit in part (a) is used to trigger the monostable multivibrator, how will the system work? Give reasons for your answer, with supporting waveforms, if required. (4 marks)
