What is a packet sink?

The packet sink takes in a stream of binary symbols that are sliced around 0. The bits are then checked for the to determine find and decode the packet. It then expects a fixed length header of 2 16-bit shorts containing the payload length, followed by the payload.

What is throttle block in GNU Radio?

The Throttle Block is typically attached directly to the output of a non-hardware source block (e.g. Signal Source), in order to limit the rate at which that source block creates samples.

What is sample rate GNU Radio?

The flowgraph provides a signal source block that operates on a sampling rate of 32 kHz. This signal is plotted using the Frequency Sink block of GNU Radio.
