What aspect of receiver analog-to-digital conversion determines the maximum receive bandwidth of a direct-sampling software defined radio (SDR)?
Sample rate✓Respuesta correcta
Sample width in bits
Integral non-linearity
Differential non-linearity
Explicación
A sampled system can represent frequencies only up to half its sample rate, so the converter's sample rate fixes the maximum bandwidth a direct-sampling receiver can digitize at once. The number of bits sets dynamic range, not bandwidth.
