Q20) This multiple choice question from DIGITAL COMMUNICATIONS course.just write for me the final answer.    Probability density function defines a. Density of signal b. Amplitudes of random noise c. Probability of error d. All of the mentioned

MCQ) 5)Quantization error------: a. decreases as the bits per sample increases b. decreases as the bits per sample decreases c. decreases as the sample rate increases d. decreases as the sample rate decreases   6)The difference between the actual value of the sample and the quantized value of the sample is called: a. PAM error b. Sampling error c. Quantization error d. PCM error       ThESE multiple choice question from DIGITAL COMMUNICATIONS course.just write for me the final answer.

Please.!!I would like you to help me with the sample study question ( with MATLAB code..!!)

A PCM communication system has 4 codewords: 00, 01, 10, 11; the first two are for positive voltages, the second two are for negative voltages. These are arranged in the way we have become used to seeing them arranged: the larger the binary number the larger the *magnitude* of the signal. The gap between codewords is 1 volt. No codeword gap straddles the 0 volts value. A 1Hz cosine with A=1.5volts is sampled at 2Hz. What is the resulting sequence of codewords?

Q24)This multiple choice question from DIGITAL COMMUNICATIONS course.just write for me the final answer.       The choice of the number of bits per PCM word depends on the a. SNR b. Bandwidth c. None of the mentioned d. SNR and bandwidth

Given 11110001 and 00001110, provide the following: AND OR XOR NOT (per individual number)

3. Some GPS receivers use 1 bit ADCS (Analog-to-digital Converters) to sample and quantize the signal i.e. the output of the ADC is simply 2 quantization levels: -1 or +1. This is typically done to save on power. (a) What is the quantization SNR? How does it compare to typical thermal noise SNR of a GPS signal before correlating with the CDMA code? (b) Justify, how come it is possible to sample the signal using a single bit and still get good performance.

For a resolution of 0.08 V, determine the seven bit sign magnitude PCM code for a sample of -2.19Va. 0101110b. 1011011c. 0011100d. 0011011 NOTE: A bit confused regarding the sign bit 0 and 1. Does 0 represents negative (-) or positive (+)?
