[USRP-users] Audio Control loop testing

Hi, I want to create an artificial audio drift in transmitter side and test it using my audio control loop in receiver. This is what I'm planning. Take an audio wav file which is sampled at 12 kHz. Re sample it such that the sample rate is now having a drift of 100 ppm, ie with sample frequenci

d clock matching, and frankly, you're not showing much progress at that over last 10 months. Best regards, Marcus On 09/16/2017 05:38 AM, Benny Alexandar via USRP-users wrote: Hi, I want to create an artificial audio drift in transmitter side and test it using my audio control loop in receiv

[USRP-users] B210 external clock and introducing drift

Hi, I'm using USRP B210 for streaming IQ data thru RF cable to my digital radio receiver. I want to use an external clock generator and feed the clock to B210. I see there are tow connector options to give external clock and PPS input. My requirement is to give an external clock and introdu

[USRP-users] Gnu radio IQ streaming

Hi, I want to stream an IQ file base band signal using usrp. The format of IQ signal is 16bit complex values of I and Q each interleaved and having sample rate of 48kHz stored in a file as follows [IQIQIQ]. I created a flow graph in usrp by selecting file block as source and used the block

[USRP-users] Py Threads

Hi All, Its known that using Python threads won't result in teh concurrency for process oriented functions. Unless you use process instead of threads you won't get concurrency in Python. How it is managed in UHD or Gnu Radio ? -ben ___ USRP-users mai

Re: [USRP-users] Py Threads

or the GNU Radio side: All GNU Radio Blocks run in their separate, "real" thread and hence are actually fully concurrent. All resulting thread-safety concerns do arise. Best regards, Marcus Müller On Sun, 2019-03-10 at 11:56 +0000, Benny Alexandar via USRP-users wrote: > Hi All, > >
