Řízené elektrické filtry s číslicově-analogovými převodníky

Abstract

Frequency selection filters have its representation in many areas of electronics and electrical engineering. This work deal with numerical drive of frequency filters concretely by numerical drive by force of digitally – analog converter. Proposal solution of numerically controlled filters is state with description basic used architectures of digitally – analog converters. Further by selection digitally – analog converter acceptable for realization of numerically controlled filters and description basic structural elements of universal filters also with presentation their numerical drive. Herself realization of numerically controlled filters is focus on measurement as parameters itself digitally – analog converter so and measurement designed numerically controlled universal filters. Simulation in simulator platform SNAP represent ideal behavior designed universal filters.
