Re: [Discuss-gnuradio] Data Rate is doubled after receiving data from USRP

2018-01-03 Thread Derek Kozel
Hello Munir, You may loose information if some operation, such as decimation which can increase the effective number of bits, was done in between the uint16 to 32 bit floating point and the conversion back to 16 bit integers. Most of the time the dynamic range of the samples isn't all signal thoug

Thank Kyeong Su Shin. Is there any chance of loosing information if I convert complex data back to 16bit as you suggested? I think it would loose information? Regards, Munir On Wed, Jan 3, 2018 at 12:16 PM, Kyeong Su Shin wrote: > Hello M.Munir, > > By default, USRP gives you data in 16bit inte

Hello M.Munir, By default, USRP gives you data in 16bit integer format (x2, for I and Q). GNU Radio's complex data type uses IEEE754 single precision (x2, for I and Q). The data type is converted by UHD (the USRP driver). Each IEEE754 data point requires 32bit of storage (or memory, bandwidth, etc

Dear All, I am confused to understand a behavior of GNURADIO USRP Source block. The problem is, 1. I connected USRP N200 with my PC. 2. I set both the cahnnels of USRP 3. I set the sampling rate of both as 5MHz 4. I connected one channel directly to the Frequency Sink Block 5. I connected the 2nd c

Hi, Does Gnuradio provide a possibility to measure a net data rate of a TCP source? I would like to output how many packets (or bits) per second are being successfully received in my top_block. Thanks Piotr ___ Discuss-gnuradio mailing list Discuss-

Hi All,    (sound stupid but...) Will the mux setup change the sample rate?  For instance:    I have 2 signals hooked up to RxA and RxB (2 diff. Rx basic daughterboards) and collecting data:    set_mux(gru.hexint(0x32103210)) be collecting less data per second than set_mux(gru.hexint(0x20202
