![]() ![]() | The abstract base class for all signal processing blocks.Basic blocks are the bare abstraction of an entity that has a name, a set of inputs and outputs, and a message queue.

The delay in the real path accounts for the group delay introduced by the filter in the imaginary path. The filter taps needs to be calculated before initializing this block |

![]() ![]() | A graphical sink to display freq, spec, time, and const plots.This is a QT-based graphical sink the takes a complex stream and plots it. The default action is to plot the signal as a PSD (FFT), spectrogram (waterfall), time domain I&Q, and constellation (I vs. Q) plots. The plots may be turned off by setting the appropriate boolean value in the constructor to False |
