Q2) Consider a digital communication system that transmits information via QAM over a voice-band telephone channel at a rate 2400 symbols/second. The additive noise is assumed to be white and Gaussian. 1. Determine the E/No required to achieve an error probability of 10 at 4800 bps. 2. Repeat (1) for a bit rate of 9600 bps. 3. Repeat (1) for a bit rate of 19,200 bps. 4. What conclusions do you reach from these results?

This multiple choice question from DIGITAL COMMUNICATIONS course.just write for me the final answer.     11)The output signal-to-noise ratio of a uniform quantizer, for a full load test tone, is equal to 61.8 dB. The number of bits per sample is a)none of the mentioned b)9 c)8 d)10

An analog signal is to be coded by an ADC. The signal contains significant frequencies up to 3.2kHz. If the system is operated at a bit rate of 36,000 bits per second (bps), answer the following: a) To avoid aliasing, the sampling frequency must be greater than or equal to kHz b) If the signal is sampled at the Nyquist rate, what is the Nyquist frequency? kHz h c) If the signal is sampled at the Nyquist rate, the number of bits per sample is number of quantization levels is and the Note: *When you use the formula bFs L in finding b, the result must be rounded up to the nearest integer.
