A subtraction circuit (24) subtracts the analog data outputted from the DAC circuit (22) from the analog data outputted from the S/H circuit (23).

One or more time slots in a SONET link may be allocated to provision a SONET circuit.

The circuit is called elementary if the path <s0, …, s(k-1)> is elementary.

The at least one processor is further arranged to configure an operation of a second circuit based on the selected operating frequency.

The primary loop forms a first continuous conductive path and the secondary loop forms a second continuous conductive path.

The selective circuit includes an inverter circuit, a flip-flop circuit, and a selector circuit.

The control circuit includes the brushed DC tubular motor, a sampling circuit, an amplifying circuit, a voltage following circuit and the discharging circuit.

The selector circuit may be integrated with a charging circuit on one integrated circuit.

Only one pair among the resistor elements composing series circuits of the bridge circuit are connected by a wiring pattern within an enclosed region (S) in which the resistor elements are enclosed.

The analog circuit transplantation is for reusing a source circuit in a target circuit.

The isolation circuit is connected between the first series circuit and the second series circuit.
