64 point FFT

[nigdi]

Hello sir,

     I want to know how to compute 64-point FFT in LabLIEW. There are 64 inputs which are complex numbers. My whole computaton has series of blocks which are given below:-

1 stage- input block

2 stage- 8-point FFT 

3 stage- Multiplier unit

4 stage- 8-point FFT

5 stage- output block.

The 8-point FFT computes FFT of first 8 samples then next 8 and so on...

Most people computing an FFT in LabVIEW would use the FFT VI (it accepts complex numbers).  However, if you need to do this for a homework assignment and show the algorithm, LabVIEW has all the matrix and linear algebra functions you need to do this.  Consult the help for details.
