In the gnuradio/gr-noaa/README file under usrp_rx_hrpt.py, there is a
reads as follows:
“The present HRPT demodulator is only tested at decimation 16. The
valid decimation rates are 24 and 32, which may work, but with more bit
other decimation rates will work.”
My (perhaps naive) question is whether the important parameter is
rate, or the sampling rate. For example, with 64 MHz USRP, a
decimation of 16 would
give 4 MHz sampling, whereas with a higher rate USRP, the same
yield a higher sampling rate.
I would appreciate it if someone could clarify this point for me.
