Q#1 Data Converters GATE EC 2025 MCQ +2 marks -0.66 marks

A 10-bit analog-to-digital converter (ADC) has a sampling frequency of 1 MHz and a full scale voltage of 3.3 V.

For an input sinusoidal signal with frequency 500 kHz, the maximum SNR (in dB, rounded off to two decimal places) and the data rate (in Mbps) at the output of the ADC are _________, respectively.

61.96 and 10

61.96 and 5

33.36 and 10

33.36 and 5

Explanation:

Given:  Resolution  bits

sampling frequency

full scale voltage (FSV)

Input sinusoidal signal frequency

Maximum SNR (in dB) for -bit resolution,

  

Data Rate  sampling frequency  No. of bits per sample  

Hence, option (A) is correct.
