If you want to estimate exactly how much a boat will move backward when the anchor rode is all chain, consider the following case. You are anchored on a calm day in 10' of water. The bow is 5' above the water. Being a traditionalist you use a 7:1 anchor rode, not forgetting to add in the height of the bow. So you have a total of 105' of chain.

In my estimation the premiums for the year that this change occurred should be maybe half of the premium of the previous year.

Hi Tal, I can't estimate the utilization of a NBFM channel off the top of my head but here is the utilization for the default B200 and B210 images. If your channelizer does not need too much block RAM and just utilizes logic blocks and DSPs then you could possibly fit something in the B210.

Yes, we calibrate every 15 min or so against blackbody loads to estimate sky temperature when doing long term measurements. However we need to find a method to make sure the USRP is in it's optimal dynamic range. In other systems we look at the time domain signals but I'm not sure how I can extract it (with sign) from I/Q samples in Gnuradio.

So, let's do a rough estimate: The AD8132 datasheet says on p.6 Input Voltage Noise is $8\,\frac{\si{\nano\volt}}{\sqrt{\si{\hertz}}}$ , so let's square that, $\SI{64e-18}{\square\volt\per\hertz}$, which over the nominal $\SI{50}{\ohm}$ is (according to P=UI and Ohm's law) means a noise power of $N=\SI{3.2e-15}{\watt\per\hertz}\approx\SI{-115}{\dBm\per\hertz

So, if you do a 256-point FFT to estimate the PSD, it might not be quite as discrete-looking as you'd like. Best regards, Marcus On 19.04.2017 07:16, Muhammad Munir via USRP-users wrote: > Dear USRP-users, > I am using USRP N200 and LFRX daughter-board.

The Correlation Estimator block sounds like it might do what you want. It will correlate against and tag your preamble, and acts as a sync block (it does not remove the preamble from the sample stream). 2.

Then maybe let's try to estimate how hard it would be to make B210 behave better. I know that B210 is low cost product (in comparison with other USRPs) and it's also low on a list of priorities in terms of support.

This is test code: I'm using tow E312 to estimate the arrive time difference between received signals.The program is explained as follows: uhd::usrp::multi_usrp::sptr UsrpDev = uhd::usrp::multi_usrp::make(“”); UsrpDev->set_time_source("gpsdo"); UsrpDev->set_clock_source("internal", uhd::usrp::multi_usrp::ALL_MBOARDS); ... uhd::stream_args_t StreamArgs; StreamArgs.cpu_format
