In the block diagram shown below, an analog signal, VIN = sin(2π10⁶t) is quantized by a 10-bit Nyquist ADC. Later, 4 LSBs are dropped and 6 MSBs are converted to an analog signal (VOUT) while using a 6-bit DAC. Assume uniform distribution for the quantization noise. The peak SQNR at the output of DAC is _______ dB.
A
61.96
B
25.84
C
49.92
D
37.88

Correct : d
