Project Information; In the project, digital filtering is required for precise weighing of a weighing system electronics. The thing to be considered here is that the filtering should have a maximum delay of 500ms and should be adaptively effective filtering against mechanical and electrical noises. Here's the problem I'm having. In the filtering I developed, there are 2000 grams on the scale. And I give mechanical vibration. 2006-1994 grams fluctuate between grams. When I increase the filter value, I reduce it to 2002-1998, but this time both the filter response is very heavy and I cannot detect sensitive grams such as 1-2 grams. What needs to be done is a fast filtering that will work in every system and I want to design a filter that provides a change between 1999-2001 when mechanical vibration comes. The filter must be adaptive. Because the vibration does not have a specific character. The frequency and character of vibration is variable.

Hi Employer, I'm excited about the opportunity to enhance your weighing system's precision through advanced digital filtering. Understanding the challenges you're facing with the current filtering process, I propose a solution that guarantees a maximum delay of 500ms while effectively combating both mechanical and electrical noises. I've encountered a similar scenario in the past where, despite reducing fluctuations with increased filter values, it resulted in a heavy response, making it challenging to detect sensitive gram differentials. My approach involves designing a fast, adaptive filter using my expertise in Embedded Systems, STM32, and digital signal processing. With a focus on C programming, I aim to create a system that seamlessly handles variable vibration frequencies, ensuring a consistent change between 1999-2001 grams during mechanical vibrations. I'm confident that my experience aligns perfectly with your project requirements, and I look forward to delivering exceptional results. Best, Ahsan

Dear Client, I hope this message finds you well. I am Avi Gupta, an experienced electronics engineer specializing in Circuit and PCB design with over 10 years of expertise. Your project on digital filtering for precise weighing perfectly aligns with my skill set. ✅ Expertise Highlight: I have successfully developed digital filtering solutions for weighing systems, specifically addressing challenges related to mechanical and electrical noise. One notable project involved implementing adaptive filtering techniques on an STM32 platform, achieving precise results with a maximum delay of 500ms. Question: Could you provide more insight into the specific characteristics of the mechanical vibrations encountered in your weighing system? ✅ Crucial Factor: The key to project success lies in developing a fast, adaptive filtering algorithm that reliably operates across various systems. Striking the right balance between responsiveness and noise reduction is essential to detect sensitive weight changes, such as 1-2 grams, during mechanical vibrations. ✅ I have spent enough time understanding your project requirements and then manually wrote the proposal and would appreciate a response as I cant message you first on the platform. Warm Regards, Avi Gupta "Quality is never an accident"
