Repeat Problem 18.3, assuming that the 8-bit A/D converter is placed inside a first-order delta-sigma modulator. What is the sampling rate if a second-order modulator is used?

Assuming a 1-bit modulator has an output signal of and the input sinusoidal signal is peak-to-peak, what is the ratio of the signal power to quantization noise power before any filtering is applied?
