Development of Colpitts-Hartley Oscillator Training Kit

Abstract

Oscillator circuits play a vital role in communication systems, particularly in generating high-frequency signals for various electronic applications. This project focuses on the design and development of a Colpitts-Hartley Oscillator as an educational training kit to support effective teaching and learning of oscillator principles. The integration of both Colpitts and Hartley configurations allows students to explore the behaviour of sinusoidal oscillations generated by the LC tank circuit in a structured and guided manner. However, students frequently encounter challenges when assembling Colpitts-Hartley oscillators manually in laboratory sessions due to the complexity of the circuitry. These difficulties often result in inaccurate connections, inconsistent measurements, and unreliable experimental outcomes, limiting students’ practical understanding of oscillator operation. To address this problem, this research was to design and test a dedicated Colpitts-Hartley oscillator training kit that simplifies circuit implementation while maintaining experimental accuracy. The results demonstrated that the kit successfully produced sinusoidal oscillations with frequencies aligning closely with theoretical, calculations and simulations, proving its reliability for hands-on learning. In conclusion, the Colpitts-Hartley oscillator training kit enhances students’ ability to understand and experiment with oscillator circuits effectively, offering a practical solution to overcome challenges faced in traditional laboratory practices.
