Laboratory experiments in electronics need to cover a wide range of technical topics and require a variety of instruments. In this Master's thesis, the use of the Red Pitaya STEMlab 125-14 is investigated for the experiments, which is used as a source of test signals, an instrument for signal acquisition and analysis, and as a programmable board for the implementation of logic circuits.
To facilitate the experiments, an interface was developed for the Red Pitaya board to perform differential measurements of analog signals, increase the range of the measured values and amplify the output signals. To validate the correct operation, measurements of the input and output frequency range were performed on the final version of the interface and compared with the design specifications.
The thesis presents proposals and expected results of laboratory experiments with analog and digital circuits in the following topics:
- rectifiers,
- detectors,
- voltage multipliers,
- broadband amplifier,
- digital FIR filters,
- UART,
- SPI.
