For the current RLC series resonant circuit experiment, its content and requirements are relatively simple and limited to the reproduction of the basic principles of resonance positioning； therefore，there is a lack of a “starting point” to guide students to think deeply about the circuit. A new cycle of research and development has resulted in the building of a non-sinusoidal signal decomposition synthesis and harmonic generation experiment box. This box is designed to have a series resonant circuit for comprehensive experiment ( Part I) which is the periodic non-sinusoidal signals decomposition and synthesis, including experimental circuit structures, experimental operation of signal decomposition and synthesis, and model validation. This guides students to explore their own tasks and enhance their own supplementary experiments. Teaching practice shows that the integrated circuit can help students improve their experiments from a different perspective. Understanding the basic principles and the value of the series resonant circuit can stimulate students to hand on experience and describe the differences between the ideal circuit model and the actual circuit. This will lead students to developing an interest in learning more. [ABSTRACT FROM AUTHOR]
