32-bit samples is a lot for an SDR though!

32-bit samples is a lot for an SDR though!
- gswdh 5y agoIt’s one or two 13 bits samples from the ADC padded out to 32 bits. True 32 bit ADCs do not exist.
- robocat 5y agoFrom article “each ADC sample contains 13 bit (I) and 13 bit (Q), that are streamed with a maximal sample rate of 4 MSPS from the AT86RF215 IC. This channel requires 4 bytes (samples padded to 32-bit) per sample (and I/Q pair) => 16 MBytes/sec which are 128 MBits/sec. In addition to the 13 bit for each of I/Q, the Tx/Rx streams of data contain flow control and configuration bits.”
