thanks for looking and please help me.
I have a 16 bit ADC sampling at 50Mhz. I take only 10 MSB and display i in my video 1024 x 768 as an output to check the signal. I see continuous line displayed in my monitor which still toggle within 1 or pixels. My question is, do I need a adaptive filter to really smooth th line in only 1 pixel wide? To make my question clear, for exampl whenever it's supposed to be a horizontal line, it has noise random pixel wide in y. Is this situation, how can I smooth the dat efficiently? I used moving average to smooth the data but every pixel i important, my moving average will give me a small wave along a straigh line plus curving the edge.
The input from ADC is dc coupled which accept level of dc voltag continuously. I'm really doubt about FIR filter and adaptive filter an can somebody tell me is this should be done in adaptive filter? I trie the DA fir from xilinx spartan 3 but it distort the signal, is that mea my cut off frequency is too low? And i use 10bit as input of adaptiv filter, should I should all 16 bit as input?
