Consider a (10,6) single error correcting code for which code polynomial is x8 + x6 + x5 + x³ + x The digital signal equivalent to the given code is line coded and transmitted. Sketch the waveform of signal using AMI coding and On-off technique and distinguish their characteristics.

a) In an audio system music signal is band limited to 5kHz.It is digitized so that the peak signal power to quantization noise power is at least 104dB. Calculate: i) The sampling rate if the signal is sampled at a rate 3.5 times the Nyquist rate; b) c) ii) The number of quantization levels; iii) Number of bits per sample. iv) Bit rate; and

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.
