What is sample rate in GNU Radio?

Note: the Sample Rate is set to 32 kHz.

What is vector source in GNU Radio?

Source that streams items based on the input vector. This block produces a stream of samples based on an input vector. In C++, this is a std::vector<T>, and in Python, this is either a list or tuple.

How do you connect blocks in Gnuradio?

In order to connect these two blocks, click once on the “out” port of the Signal Source, and then once on the “in” port of the Scope Sink. The following flow graph should be displayed. 7. You may have noticed a warning in the message window indicating that the flow graph may not have flow control.

What is rational resampler?

Rational resampling is the process of converting the sampling frequency of a signal to another sampling frequency that differs from the original frequency by a rational factor of L/M, where both L and M are integer values. Rational resampling also is known as fractional resampling.
