rectifizierte

Rectifiziert (rectifiziert) is the past participle or adjective of rectifizieren, a German verb meaning to correct, straighten, or convert according to a standard. In technical contexts it denotes something that has undergone a rectification process.

In electrical engineering, rectification converts alternating current (AC) to direct current (DC). A rectified output is described as rectifizierte Gleichspannung or rectifizierte Wechselspannung, depending on the resulting form. Devices such as diodes and rectifier bridges perform half-wave or full-wave rectification; smoothing capacitors reduce ripple, yielding a more stable DC voltage.

In signal processing and measurement, rectification transforms a signal to be nonnegative, typically by taking the absolute value. Half-wave rectification preserves one half-cycle, while full-wave rectification inverts or flips negative portions to positive. Rectified signals are common in envelope detection, amplitude analysis, and instrumentation.

In mathematics, a curve is rectifiable if its length is finite. Rectification refers to defining the arc length of a curve via an integral or polygonal approximations. While simple curves such as polylines are rectifiable, certain complex or fractal curves may be non-rectifiable, having infinite length.

In photogrammetry and cartography, rectification (Rectifikation) maps images to a standard coordinate system, removing perspective distortion to align with geographic data. Orthorectification further accounts for terrain elevation to produce geometrically correct, planimetric images suitable for measurement and GIS integration.

Etymology: rectifies from Latin rectus “straight, right” through French rectification, entering German as rectifizieren and rectifiziert. The term is used across domains to indicate that an entity has been corrected, aligned, or converted according to a defined method.
