Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a Class B amplifier design, calculate the conduction angles of its transistors. Discuss the impact of the biasing method on crossover distortion.

💡 Hint: Assess if adjustments to the biasing impact operational smoothness.

Challenge 2 Hard

Modify a Class B amplifier design to change it into a Class AB design and analyze the effects on audio output quality.

💡 Hint: Draw the impact of smoothing curves to demonstrate performance.
