AI Technical Summary
Traditional ECG signal acquisition and processing circuits are fixed designs that cannot meet the diverse needs of different signal characteristics and noise backgrounds. Students find it difficult to intuitively understand the function of analog circuits by adjusting parameters, and there is a lack of experimental diversity and flexibility, resulting in a disconnect between teaching content and scientific research practice.
An adjustable analog signal acquisition circuit was designed, including a multiplexer and a precision resistor and capacitor network, to achieve dynamic adjustment of filter frequency, gain and bias level. Combined with modular design, it covers functional modules such as low-pass filtering, band-pass filtering, level adjustment and signal amplification, and supports a variety of ECG signal processing experiments.
Students can gain a deeper understanding of analog circuit design and application by dynamically adjusting circuit parameters, improve the flexibility and diversity of experiments, meet the needs of complex experiments, cultivate hands-on skills and problem-solving abilities, and bridge the gap between teaching and scientific research practice.
