I am attaching the schematic of a circuit. I need to power up this entire circuit using batteries. Basically i need two sets of voltages, "+-12 V for the opamps and +-6 for the 50Kohm resistor in the schematic.(This is not my design). If anyone has an idea how can I do this I would be very much greatful if you can share that with me. I would really appreciate if you can explain the power circuitry design please.
Thank you.
