Question

a) Design a circuit using 741 op amp IC and 555 timer IC, to generate both Pulse Width and Pulse Position modulated signals. Perform the required calculations to obtain the width of the PPM signal as 200μs. Draw the clear circuit diagram and calculate the values of resistors and capacitors used. b) Simulate the circuit designed in part (a) using appropriate simulation tools(Multisim or Tinkercad) and obtain the output. The answer should include details such as aim, brief procedure, screenshot of simulation circuit along with resultant waveforms and calculations of the practical time-period obtained for PPM output. c) Plot graphs with clear labels and scales for message, carrier and output signal (PWM and PPM). Also discuss your inference and reflection on the results obtained. [Note: Plot graphs on a normal graph paper by hand and attach the scanned copy to the assignment]
