fir filter design - newbie

dear kaz,

thanks for your response, please, i dont have enough idea about this thing, i know only theory little of dsp, and i dont have much idea about matlab. since my lab access time is very limited to us, due to vacation. please could you tell , what is the if 13.5 mhz is the sampling frequency, and pass band and stop band, and my instructor told me to use 7 tap filter, i tried with fdatool, and take the coeffs. and put that coeff in vhdl. architecture and all fine. only this filter coeff, is a headache for me. because some time the image is so bleeding,

thanks and regards,

baba
