The power spectral density of a WSS information source is shown below (the unit of power spectral density is W/Hz). The maximum amplitude of this signal is 200.
1. What is the power in this process?
2. Assume that-this signal is transmitted using a uniform PCM system with 512 quantization levels, what is the resulting SQNR in decibels and what is the minimum required transmission bandwidth if in sampling the signal a guard band of 1 kHz is used?
3. If the available transmission bandwidth is 47 kHz, design a PCM system that achieves the highest possible SQNR and utilizes the maximum guard band.
