Question: An input signal ranges in amplitude from +1 V to -1 V, which matches the dynamic range of the ADC being used. No clipping of the input signal occurs, and the signal amplitude is equally likely across the full dynamic range of the ADC. If each sample is uniformly quantized to 16 bits, what is the approximate signal to quantization noise ratio (SQNR) in dB? Assume no noise shaping or other advanced techniques are being used in the ADC design.
