WebMar 6, 2024 · Sorted by: 1. Two things: there's a bug in your expectation: the sum of all powers needs to be around 1, i.e. 0dB, because that's the power and thus the variance, so the individual bins need to be lower - in fact, the lower the longer your FFT is. But there's also undocumented scaling in the frequency sink, so we can call that a GNU Radio bug ... This flowgraph shows how the FFT block can be used to reproduce the behavior of the QT GUI Frequency Sinkblock. Both outputs match, but … See more
WebTherefore, the discrete Fourier transform (what's shown on the GUI sink) will be a mirror image for any real function. Because of this, for a real function the negative half of the discrete Fourier transform doesn't really tell you anything. It's a common enough case that within the setting for the GUI sink there's an option to hide it. WebThis document focuses on how to set up a flow graph in GNU Radio Companion that will measure the phase of an RF signal using a Software Defined Radio (SDR) . ... Using …

WebThe FFT block needs to know when the SDR has been retuned to a new frequency, so it uses a gnuradio timestamp and frequency tag provided by the gnuradio UHD driver upon retuning. This tag functionality has been added to the Soapy driver in a gnuradio fork which is part of gamutRF, so that other SDRs may be used as scanners. ... Graph the most ...
