About ADC_DelSig to Filter signed problem
Hello I am still trying to filter a signal. I had another problem but them solved. Firstly I am using ADC delsig after I am sending them to Digital Filter Block via DMA. My question is about ADC delsig output is signed integer. When I send them to filter to DMA, my signal get 2's complement form because DMA block allow to send 32bit unsigned integer . To solve them I add 1V DC offset from signal generator to test the code . My question is that can I solve it to another method because there would be problem to measure the my real signal. Anyone has an experience about that.
