Titel auf Englisch: Data Converters
Lernergebnisse
The students are familiar with the structure and application of Nyquist rate and oversampling AD and DA converters. They understand the specification, areas of application, advantages and disadvantages of the respective converter and can make an appropriate selection for an application. They can describe a Nyquist rate and delta sigma ADC in Matlab / Simulink and simulate the specification.
Inhalte
- Repetition of basics: sampling, quantization, noise, DFT, windowing, Z-transformation
- Specification: operating modes, static and dynamic properties, test of DNL, INL, distortions
