Introduction
Think you are wellversed with the ABC of Electronics? Quark 2010 gives you a chance to test your skills in analog electronics and electrical manipulation with the basic blocks which have engineered a technical revolution. AnalogTrix is all about circuit design and assembly. It provides promising youngsters a platform to compete with fellow designers and gadget freaks and prove your mettle. Let the high voltage spark your imagination.
Event Specifications
The event has 2 rounds:
Round 1
 Time Limit: Participants will get a maximum of 3 hours to simulate their circuits and display the output.
 Participants are required to design (simulate) a circuit to determine the values of Resistance, Inductance and Capacitance in an LCR series circuit.
 The challenge is to do all the computations using basic electronic components like resistors, capacitors, opamps etc. One has to design circuits to perform mathematical operations like addition, subtraction and so on in order to solve for the values of R, L and C.
 Participants will be provided with the resonant frequency of the circuit. The resonant frequency value multiplied by any suitable constant or the product of L and C with any constant (i.e. K* L*C) of the LCR series circuit can be used by the participants as input data for the circuit design.
 E.g.: L=1mH, C=1mF, then f resonant = 159.2Hz and LC = 10^6. Participants can multiply these values with any constants, say, 10^2 and use it as an input data to their designed circuits.
Round 2
 Time Limit: Participants will get maximum 3 hours to simulate their design and display the output.
 At the end of Round 1 each team will be given a figure. The objective is to design and simulate a circuit to produce that figure as the output. Each team will have a complete day (Day 2 of Quark 2010) to design their circuit.
Rules
Round 1
 Time limit for this round is 3 hours
 The participants will be provided with NI MultiSim (30 day trial version) or CAD PSPICE 9.1 to simulate their design. Standard libraries will be provided.

The circuit will be tested for the following 3 sets of R,L and C values:
 R=5kΩ, L=150uH and C=10uF
 R=10kΩ, L=100uH and C=500uF
 R=10kΩ, L=250uH and C=760uF

Other than these 3 sets the circuit will be tested with one more combination of R, L and C values which will be revealed to the participants during the evaluation of the circuit. The range for this set will be as follows:
R: 1k to 10k ohm
L: 10uH to 1mH
C: 10uF to 1mF
 Participants can display their values in any suitable units and scale. The values of R, L and C may be scaled as per the choice of the participants. Accordingly proper explanation for the chosen scaling factor should be provided.
 E.g.: L=10uH may be represented as 1V and 100uH can be represented by 10V (Scaling factor is 10^5).No change should be made in any part of the circuit for different sets of R, L and C values.
 A maximum of only 2 branching points are allowed. Branching across all R, L, and C is not allowed. E.g: 2 branches, one across R and another across L and C together as shown in Figure 1(a) is allowed. But branching as shown in Figure 1(b) is not allowed.

Figure 1(b)
 Only basic electronic components like opamps, transistors, resistors, capacitors, diodes and inductors along with sine or square wave generators can be used.
 The voltage value at any node or the current value at any node in the circuit can be used as the output.
 Participants are required to design their circuit from the beginning during the time provided to them on the day of the event. But they are allowed to carry with them a hard copy of their circuit or any material that they feel necessary. Soft copies are not allowed.
Round 2
Time limit for this round is 3 hours

The participants will be provided with NI MultiSim (30 day trial version) or CADPSPICE to simulate their design. Standard libraries will be provided.

The number of output probes allowed will be disclosed along with the figure.

Any analog electronic component with less than 32 pins is allowed. Microcontrollers are not allowed.

Only one kind of input is allowed  either sine, square or triangle wave.
 No power source other than the standard voltages to power the ICs can be used. A DC voltage source cannot be used as an input to the circuit. However participants are allowed to use DC voltage sources less than 15V to manipulate voltages at any part of the circuit*
These rules are subject to change. Any change in rules will be notified through the website. Participants are requested to keep themselves updated.
Team Specifications
Each team can comprise of minimum 1 member and maximum 3 members.
Judging Criteria
The following will be the criteria used for judging:

*Exact marking scheme will be put up soon. Final points will be based on cumulative points of both the rounds.
Resources
Participants are not required to carry anything specific for the event. Computers with CADPSPICE 9.1 and MultiSim installed on it will be provided.
Eligibility
All participants of Quark 2010 are eligible to take part in the event. But each team has to submit an abstract of their circuit design for Round 1. Selection of teams for the event will be based on the abstract that they submit.
The abstract should have the following:

Proper explanation of the logic and method the team intends to follow for solving the problem statement.

The circuit as developed till the date of abstract submission.
