Re: [Discuss-gnuradio] Continuously Write FFT Samples to a File

[Mallesham Dasari]

If you are trying to print just the FFT, it should not be an issue. If you print raw iq samples, then you will run out of memory. By long, you mean how long? Days?

Hasini,

can you please re-state what you're trying to do? That might help you

Cheers,
Martin
