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.
