hi,
i need help in sampling(matlab coding) a four channel AM modulated signal each
at carrier frequencies 400Hz,1000Hz, 1600Hz and 2600Hz respectively...

how will i sample my signal in such a way that 400Hz signal spectrum gets
repeated at zero carrier frequency, so that i can apply a LOW PASS FILTER to
extract my very first channel...

kindly help me out...

regards
Nosheen
