Hello Raspberry Pi Community,
I'm working on a project that involves using the AD7924 ADC chip with a Raspberry Pi for tube PCR applications. Our main challenge has been dealing with noise, specifically at the 55Hz frequency, which significantly affects signal integrity. Despite employing basic noise reduction strategies, we're looking for more effective solutions to enhance data quality.
We've utilized Python for data acquisition and MATLAB for analysis, implementing a moving average filter based on the identified noise frequency and sampling rate. While this approach has shown some success in reducing noise, we believe there might be room for improvement or alternative strategies that we haven't considered.
I'm reaching out to see if anyone has experience or insights on the following:
1. Advanced hardware modifications or setups that have proven effective in similar high-precision ADC applications.
2. Software or signal processing techniques, beyond moving average filtering, that could further minimize noise impact.
3. Experiences with real-time noise reduction in data acquisition systems, especially in contexts requiring high fidelity like PCR.
Any guidance, references to relevant studies, or personal anecdotes on tackling ADC noise in sensitive applications would be immensely valuable. Thank you for sharing your knowledge and helping enhance the reliability of scientific instrumentation.
Thank you in advance for your help!
