# How to calculate SNR of dead-band quantizer?

Suppose we have a dead-band quantizer with $$\ N = 5 \ quantizing \ levels$$ which uses $$\ b = 3 \ bits$$ for each produced symbol. The quantizer gets as input a uniformly distributed signal $$\ X$$ at the interval $$\ [-10,10]$$. How can I calculate the signal to noise ratio $$\ SNR$$ of the quantizer ?
