Werner Almesberger	b3c0b4bf62	usrp: update filtering and display for uncorrupted measurement setup ... We now have a much wider dynamic range of the signal (with better SNR). The outliers are mainly WLAN interferences. - usrp/evscan: changed threshold from -50 dB to -70 dB - usrp/evscan: increase outlier tolerance from 2 dB to 10 dB - usrp/plscan: changed display range from [-35:-25] to [-40:-5]	2010-12-01 11:08:16 -03:00
Werner Almesberger	83d216244c	usrp: support DCT in addition to complex FFT ... - usrp/evscan (usage, main): treat all arguments but the last as options and pass them to "fft" - usrp/fft.c (fft_complex, do_fft): moved actual FFT calculation to separate function - usrp/fft.c (fft_real, do_fft): added real-valued FFT (DCT) as alternative - usrp/fft.c (main): undocumented option -a to set the FFT algorithm	2010-11-26 12:16:34 -03:00
Werner Almesberger	3684c0765a	usrp/: new tools to run, evaluate, and plot a full frequency scan ... - usrp/fscan: perform a frequency scan in my test setup - usrp/evscan: determine the frequency-dependent signal strength from a frequency scan - usrp/plscan: plot one or more data sets produced by evscan	2010-11-17 13:12:56 -03:00
