Hello everyone!
In my design ,the frequecy of signal is about 1MHz,but my sampling rate is 200MHz,Can someone tell me what is the effective method to decrease the affect of noise?(FIR is not realizeable).

If you can change the hardware a little, put an analog low-pass filter in front of your A/D. This will suppress the out of band noise.
