Re: [Discuss-gnuradio] [ Calculating the amplitude of a signal source ]

Hi all,

I have recorded a sinusoidal USRP signal (generated by a vector signal generator) in its complex form in a file_sink. I understand that the file_sink will have the I-Q data of the signal. 

Can anyone tell me in what format that I-Q data will be stored i.e 
(i)  How many bites does each I or Q component take?
(ii) What will be their pattern in the file_sink i.e whether they would be in (I1, Q1, I2, Q2 ... Ik, Qk) form OR (I1, Q1, I1, Q1, I2, Q2, I2, Q2 ..) sequence OR any other sequence?

My purpose is to parse the I-Q data from the file_sink.

Have attached the WX_GUI_Sink plot of the signal received in complex form (in GRC).

Thanks and Regards,
