Lecturer:

Michal Janošek, Josef Vedral

Tutor:

Michal Janošek, Josef Vedral

Supervisor:

Department of Measurement

Synopsis:

The course is dedicated to methods for preprocessing, digitalization and reconstruction of continuis signals. It is focused to the methods for achieving of high precision of transmission and suppression of spurious components. The laboratory exercises are divided into two parts: the first part is classical tasks; the second one is individual project of design of typically data acqusition system. The teaching is supported by the CAD system for measuring circuits.
