gnuradio.fft

Fourier-transform blocks and related functions.

gnuradio.fft.ctrlport_probe_psd(std::string const & id, std::string const & desc, int len) → ctrlport_probe_psd_sptr

A ControlPort probe to export vectors of signals.

This block acts as a sink in the flowgraph but also exports vectors of complex samples over ControlPort. This block holds the latest number of complex samples so that every query by a ControlPort client will get the same length vector.

Constructor Specific Documentation:

Make a ControlPort probe block.

Parameters:

• id – A string ID to name the probe over ControlPort.
• desc – A string describing the probe.
• len – Number of samples to transmit.
