Hey Guys, how are you all doing? i have a project to do and im not sure if im doing it right .. the professor gave us a file to filter by doing a matched filter .. i loaded the file .. then what i did for the matched filter is that i defined the impulse response for the filter by a number of ones and zeros and then i flipped the input from the file by using the fliplr .. and then i convolved the flipped input with the impulse response...is this how a matched filter should be done ? is it right..? or is there another way that i could implement a matched filter to filter out the file..? please help me .. Thank You .. |

Hi, The procedure seems to be correct, but I did not understood the line "then what i did for the matched filter is that i > defined the impulse > response for the filter by a number of ones and > zeros" How can you define the impulse response of the filter like that? -SaiRamesh. --- xoticsmile <> wrote: > > Hey Guys, > how are you all doing? > i have a project to do and im not sure if im doing > it right .. > the professor gave us a file to filter by doing a > matched filter .. > i loaded the file .. > then what i did for the matched filter is that i > defined the impulse > response for the filter by a number of ones and > zeros and then i > flipped the input from the file by using the fliplr > .. and then i > convolved the flipped input with the impulse > response...is this how a > matched filter should be done ? is it right..? or is > there another > way that i could implement a matched filter to > filter out the file..? > please help me .. > Thank You .. > > __________________________________ |

hi,
im not sure if i said it write or not..
but what i did is that i loaded the file
then i defined
h=[ones(1,50) , zeros(1,50)];
for the matched filter and then i convolved the flipped signal with h
... is that write .. or is there another way to implement a matched filter
?
thank you
