Abstract
A band-pass filter is described comprising a first first-order filter stage comprising a first resistor characterized by a first impedance and connected to a first node, referred to as a filter input node, and, through a second node to a first reactive component connected to a third node, the first impedance being such that a first current therethrough is dependent on the difference between the voltages at the first and second nodes; and a second first-order filter stage comprising a second resistor characterized by a second impedance and connected to the second node, and, through a fourth node, to a second reactive component connected to a fifth node. The second impedance is such that a second current therethrough is dependent on the negative of the sum of the voltages at the second and fourth nodes. The band-pass filter further comprises summing means for summing the voltages at the second and fourth nodes to output a voltage at a sixth node.
