hello!(adsbygoogle = window.adsbygoogle || []).push({});

i'm given a signal h(t) = v(t)*g(t)

where g(t) is a distortion/noise that got added

and has a very low frequency compared to v(t)

i need to devise a method to clean up g(t)

i'm thinking of to do the fft on the signal h(t),

and remove the lower frequencies and do the inverse fft,

but this might not just remove g(t), but it may as well remove v(t)

any hints?
