Event - Wavefront

Prizes worth Rs 15000 up for grabs for this event. Make the most of this opportunity and register now!

"Pied Piper without a flute. Make the input signal literally dance to your tune in as many ways as possible to get the required output."

The aim of the event is to achieve the given output waveform from the specified input waveform with maximum number of distinctly different intermediate outputs stages (no stage can be repeated) in as many methods as possible. The input and output waveforms are given below.There will be a second on the spot round conducted by National Semiconductor. Problem Statement for the second round will be given during the event.

Judging Criteria

Credits will be given for the implementation of each of the above requirements based on the formula given below.


  • Each team may consist of a maximum of 4 members.
  • The input signal can be applied across only one terminal.
  • Use of microcontrollers/microprocessors is not allowed.
  • The waveform generated at the intermediate stage of any method cannot be repeated at any stage thereafter in that method (including the input and output waveform).
  • The test points at each intermediate output stage must be clearly specified and the output at each of these stages should be shown on a CRO (Failure to do so will result in the stage not being considered as an intermediate stage).
  • The circuit diagrams for each method must be submitted to the organizers before the event.
  • The participants should be able to provide an explanation for each circuit if asked.
  • Each team will be given some time to setup their circuits prior to the competition.
  • Judges decision will be considered final and binding.

Input and Output Waveforms:

  • The input signal is 1 kHz. sine wave with a peak-to peak voltage between 8-10 V.
  • The output is below the positive X-axis. The peak value of the output waveform must
    be GREATER THAN OR EQUAL TO 2.5 V as shown.
  • Only the input signal and DC power supply can be fed to the circuit.
  • The output must be generated from the input signal ONLY and not from the power


Points System:

  • Each intermediate step in each method will be evaluated out of 10 points depending on closeness of the CRO output to the desired output.
  • 50 points is allotted for achieving the final waveform for each method (Obviously closer to the desired output, more the pts).
  • 20 points is allotted for innovativeness, safety and good practices for each method .
  • The total points will be the sum of the points for each method

  • Eligibility

    All students with a valid identity card of their respective educational institutes are eligible to participate in the event.

    Special Note

    • The decision of the judges shall be treated as final and binding on all.
    • The organizers reserve the rights to change any or all of the above rules as they deem fit. Change in rules, if any will be highlighted on the website and notified to the registered participants.
