    Question about FFT of a real signal

    Re: DSP and Real signal i) Do overlap and save if you use convolution also. ii) Do shifting will also help you. by using sliding concept bye sanbaba

    Interpolation (upsampling)

    There are two methods 1. between each samples add 7zeros and take LPF. 2. If u want to take interpolation for 50 samples first take fft of 64 samples by padding zeros. Consider only 33 values. add 224 zeros to it (224+257) Take ifft of 512 samples. These two methods explained in Scientist and...

    FFT Plot of audio signal (MATLAB)

    write like this. y=wavrecord(5*11000,11000,'double'); yfft=fft(y); freqz(yfft); you'll get both the magnitude and phase. Bye sanbaba

    simulink to matlab???

    simulink is just to simulate. If you want you can use mex file based things. you can get better idea from codeproject.com Bye Sanbaba

    Useful FFT code you can use this.

    fft(short int dir /* This computes an in-place complex-to-complex FFT x and y are the real and imaginary arrays of 2^m points. dir = 1 gives forward transform dir = -1 gives reverse transform */ short FFT(short int dir,long m,double *x,double *y) { long n,i,i1,j,k,i2,l,l1,l2...
