An ideal quantizer takes an sinusoid without overloading and quantizes it with an LSB step size of 5 mV. What is the resulting SQNR?

An input signal arrives at a quantizer already corrupted with some noise and having a SNR of 35 dB. How many bits of resolution does the quantizer require to ensure that the quantization noise is at least 3 dB smaller than the input noise?
