thank u very munch for giving reply..

but what my problem is that... i have data at different frequrncies...i.e.,

20MHz - 0.2+1j v
40MHz - 0.5-0.2j v
...................
1.5Ghz- 8-1j v (total 75 samples)

After i converting this data to time domain using ifft. But what the problem is that how to represent the X-axis values in time domain properly.

please suggest how to do this one
