Dataforth - Analog I/O Isolation Module Options. Including Analog Signal Filter Control. (181 words) |
 | Analog I/O modules filter, isolate, amplify, and convert analog signals for use in thousands of test, measurement, and control applications. |
| Each analog module incorporates a 5- or 6-pole analog filter. |
| Each analog module is input protected to 240VAC continuous. |

Analog Filter Design Demystified - Maxim/Dallas (2304 words) |
| The guru of analog engineers is the Analog Filter Designer, who sits on the throne of his kingdom and imparts wisdom. |
| Analog electronics has two distinct sides: the theory taught by academic institutions (equations of stability, phase-shift calculations, etc.), and the practical side familiar to most engineers (avoid oscillation by tweaking the gain with a capacitor, etc.). |
| To ensure conformance with the generic filter described by equation 4, and to ensure that the last term equals unity, the first two quadratics have been multiplied by a constant. |
