Null to null bandwidth definition
WebThe Half Power Beamwidth (HPBW) is the angular separation in which the magnitude of the radiation pattern decrease by 50% (or -3 dB) from the peak of the main beam. From … WebDescription. bw = obw (x) returns the 99% occupied bandwidth bw of the input signal x. example. bw = obw (x,fs) returns the occupied bandwidth in terms of the sample rate fs. example. bw = obw (pxx,f) returns the 99% occupied bandwidth of the power spectral density (PSD) estimate pxx. The frequencies f correspond to the estimates in pxx.

This happens at Rsym Hz. We will ignore all of the other bumps in the graph since they are so much smaller.
