An SDR receiver is overloaded when input signals exceed what level?
One-half of the maximum sample rate
One-half of the maximum sampling buffer size
The maximum count value of the analog-to-digital converter
The reference voltage of the analog-to-digital converter✓Richtige Antwort
Erklärung
The analog-to-digital converter can encode input voltages only as far as its reference voltage, and beyond that the samples clip at full scale and the resulting distortion spreads across the receiver's passband. Sample rate and buffer size govern bandwidth and processing depth, not amplitude headroom.
