Answer:
10
Step-by-step explanation:
From the information given:
The input for a fixed voltage range for SQNR when N = 7 is 32 dB
Required: To find the minimum value of N such that SQNR ≥ 46 dB
For an ADC:
SQNR = 6.02(N) + 1.76 dB
Comparing both SQNR such that SQNR₁ = 32 dB and SQNR₂ = 46 dB
Taking the ratio:
