The picture is a positive-negative double supply circuit which is usually adopted in the analog circuit.It is a power sipply circuit formed by tapped full-wave rectification and three terminal regulator.The ground of smoothing capacity C1,C2 and regulator is connected to A point on the tapped landline of transfer. Point A is a reference potential.The supply output will not be effected by the smoothing current of C1 and C2.
