What is Class B and AB Amplifier Analysis about?

The document describes an experiment to examine class B and class AB power amplifiers. Class B amplifiers have an efficiency of up to 78% but introduce crossover distortion when the input signal crosses zero. Class AB amplifiers reduce this distortion by having a duty cycle greater than 50%. The experiment involves building class B and AB amplifier circuits and measuring the crossover distortion and its reduction at different frequencies and load conditions. Power transfer to a miniature speaker load is als
