Lock-in Amplifier
Pivnička, Martin ; Šír, Michal (referee) ; Beneš, Petr (advisor)
This thesis deals with coherent demodulation by using Lock-in amplifier. The first part of this thesis focuses on theoretical analysis of this issue. The second – practical part describes design, construction and measurement of single–channel and dual–channels analog Lock-in amplifier. Further is described measurement of flow through the Coriolis flow meter by using dual-channels Lock-in amplifier. As further is described design digital Lock-in amplifier by using measuring card. The conclusion summarizes the results of measurement of Lock-in amplifier.
