Revision as of 19:31, 16 April 2022 by AlchemX (Corrected obvious copy-paste mistake. Quadrature rate for the RECEIVE block is the INPUT sample rate. and I saw this mistake also exists in the python block definition on GitHub ;).)
Narrow Band FM Receiver.
Takes a single complex baseband input stream and produces a single float output stream of audio sample in the range [-1, +1].
- Audio rate
- Sample rate of audio stream, >= 16k (integer)
- Quadrature rate
- Sample rate of input stream (integer). Must be an integer multiple of Audio rate.
- Preemphasis time constant (float)
- Max deviation (R)
- Maximum deviation in Hz (float)
This flowgraph shows a NBFM Receive block in a working 2 meter receiver.
