Design a simple electronic circuit for combining three analogue signals.

Item 1: Produce the circuit design

- The three signals are very low-level, noisy sinusoids. They are to be combined to give a signal with better SNR.

- The signals may have different amplitudes.

- The input frequencies are low: around 2,000 Hz.

- The signals are in phase, or 180 degrees out of phase (may have opposite sign).

- The circuit should work for inputs over the range <0.1 mV up to 1000 mV.

- Inputs to the circuit should be high impedance.

- The circuit should work with 3 V power.

- The circuit components should be as cheap as possible, for a consumable product.

- Provide a listing of the components with supplier and prices.
