Course detail

Biosignals Acquisition and Processing

FEKT-MPC-SADAcad. year: 2026/2027

The course focuses on describing and designing the acquisition path from the origin of a physical signal to converting it into digital information. It provides knowledge in the field of physical transducers of electrical and non-electrical quantities and presents analog signal processing techniques such as amplification, rectification, filtering, comparison, and detection of extreme values. It also deals with signal transmission, multiplexing, modulation techniques, and analog-to-digital converters. The course covers voltage references, DC/DC converters, and the design of isolation amplifiers.

Entry knowledge

Work in the laboratory is conditional on holding a valid qualification as an “instructed person” (§ 4 of Government Regulation No. 194/2022 Coll.), which students must obtain before classes begin. Information regarding this qualification is set out in the Dean’s Directive “Informing Students about Safety Regulations.

Rules for evaluation and completion of the course

The conditions for successful completion of the course are:
  1. attendance at laboratory exercises,
  2. passing the mid-term test (20 points),
  3. passing the final exam (80 points).
More detailed information is specified in the updated announcement issued by the course coordinator before the start of the relevant semester.

Aims

Students completing the course will be able to define and describe the basic types of physical signals, converters, and acquisition path blocks. They will be able to explain the principles of analog signal processing, including amplification, filtering, outlier detection, and modulation. Graduates will be able to design and implement basic circuits for analog signal processing, including filters, comparators, and converters. They will also be able to analyze signal path characteristics, identify potential sources of error, interference, and distortion, and assess their impact on the resulting measurement. Graduates will be able to design and assemble an acquisition chain with regard to the origin of the signal, the application context, and subsequent signal processing.

Study aids

Recommended sources, lectures, knowledge acquired during laboratory exercises.
