Determine the range of the uniform quantizer

Question

Assignment:

1. A signal has exponential bilateral probability density function with mean 1 Volt and variance σ²a = 2V² Determine the preprocessing for this signal, the range and the number of bits of the uniform quantizer to guarantee a signal-to-quantization noise ratio of 42 dB. Assume p_sat ≤ 10^-3.

2. The information signal a(t) has uniform probability density function over the interval (-5, +5) V. Determine the range of the uniform quantizer and the number of bits necessary to achieve a signal-to-quantization noise ratio of 40 dB.
