This study explores the characteristics and applications of RC (resistor-capacitor) low-pass and high-pass filters, focusing on their gain versus frequency response, advantages, limitations, and practical significance in electronic circuits. A detailed theoretical analysis is conducted to understand the role of these filters in signal processing, emphasizing their ability to attenuate specific frequency components and shape signal waveforms. The research also includes an experimental investigation, where an RC circuit is implemented using discrete components and analyzed with the ADALM1000 active learning module and PixelPulse2 software. The cutoff frequency and filtering behavior are examined through direct measurements and the results are compared with MATLAB-based simulations. The experimental results align closely with theoretical predictions, confirming the effectiveness of RC filters in noise reduction, frequency selection, and signal conditioning. By bridging theoretical concepts with practical validation, this study underscores the importance of RC filters in modern electronics. The insights gained from this research provide valuable guidelines for optimizing filter design in applications such as audio processing, communication systems, and embedded electronics.

摘要

This study explores the characteristics and applications of RC (resistor-capacitor) low-pass and high-pass filters, focusing on their gain versus frequency response, advantages, limitations, and practical significance in electronic circuits. A detailed theoretical analysis is conducted to understand the role of these filters in signal processing, emphasizing their ability to attenuate specific frequency components and shape signal waveforms. The research also includes an experimental investigation, where an RC circuit is implemented using discrete components and analyzed with the ADALM1000 active learning module and PixelPulse2 software. The cutoff frequency and filtering behavior are examined through direct measurements and the results are compared with MATLAB-based simulations. The experimental results align closely with theoretical predictions, confirming the effectiveness of RC filters in noise reduction, frequency selection, and signal conditioning. By bridging theoretical concepts with practical validation, this study underscores the importance of RC filters in modern electronics. The insights gained from this research provide valuable guidelines for optimizing filter design in applications such as audio processing, communication systems, and embedded electronics.
