Stereo audio amplifier with class D and SD modulation for laboratory measurements
 Kováč, Martin ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
This thesis deals with the technology of amplifiers with sigma-delta modulation. The primary aim was to the design and testing of an amplifier with sigma-delta modulation and its use in laboratory exercises in the subject BPC-AUD. In the power part, the SSM3302 stereo amplifier from Analog Devices is used, which uses three-layer output sigma-delta modulation. This amplifier will deliver output power into a 4 load. Part of the work is the design and construction of a control block consisting of a correction amplifier controlled by digital potentiometers from Arduino nano.
