What aspect of receiver analog-to-digital conversion determines the maximum receive bandwidth of a direct-sampling software defined radio (SDR)?
Pick an answer to check it.
Answer: A. Sample rate
By Nyquist, a direct-sampling SDR can cover at most half its sample rate. The faster the ADC samples, the wider the bandwidth it can receive.
Tip: Sample rate sets bandwidth.
