Abstract

This thesis deals with the possibilitiesof measuring THD (Total Harmonic Distortion) for amplifiers class A and class AB. Using a measuring card MF624, as an analog input and output, and its petting in Matlab, cpou can evaluace there sultsof harmonic distortion THD and image sofwaveformmeasured sinals. The first part of this thesis will a more detailed description of eachamp types, thein characteristics, general parameters of amplifier, distribution amplifiers working classes. Theaim of the measure and thus of the whole the is will theexten tof distortion in aplifiers class A and class AB, calculationusinf Fourier series in theamplitude-phaseregistration.
