Mostová měření pasivních elektrických veličin – laboratorní úloha

Abstract

The goal of this bachelor's thesis is the design and realization of a bridge circuit which will be capable of measuring passive variables such as rezistance and capacitance of given components. Theoretical part of this thesis concerns individual types of bridge circuit connections for each of the passive variables. This part is supplemented by basic shemes of connections and a formula used for calculation of other important elements in these connections. The practical part focuses on design of schema , the construction of printed circuit board and the design of rezistance and capacitance decades. The testing part focuses on the measuring accuracy where the outcome is compared to the value declared by the manufacturer of given component
