hii....i want code for a chirp signal.......in c language ...... matlab code is: fs=3e9; //sampling freqncy=3000MHZ t=0:1/fs:1023/fs //time y=chirp(t,940e6,1023/fs,106e7); figure(1); specgram(y,256,fs,256,250); n=2; point=256; for m=1:256:1024; k=y(m:m+point-1); z=fft(k); figure(n); plot(abs(z)); n=n+1; end aim of our project is 2 extract a linear FM signal ..i.e.,chirp signal which we receive 4m our enemy target.......4 dat v need 2 rite the bove code in "c" language...... cud nyone plz help me in dis.....
