# Matched Filter

Started by December 25, 2004
 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  nammi sairamesh wrote: Hi,The procedure seems to be correct, but I did notunderstood 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 filterlike 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 ..__________________________________ Send holiday email and support a worthy cause.
