Express your answer in dB. We have discussed in earlier sessions about the parameters used in Amplitude Modulation. That is, the constellation in Fig.

As a consequence, X and Y are independent. Execute the script and print or sketch the four graphs. Otherwise, the demodulator produces hard outputs that are processed by a hard-decision decoder.

Jobs in Meghalaya Jobs in Shillong. This is done by checking that there is always a transition in the middle of a bit period. Discuss the advantages and disadvantages of digital processing versus analog processing. Express your answer in terms of the Gaussian Q-function.

Determine the minimum number of quantization levels L required, assuming that m t is sinusoidal. To determine the parameters, each one has its own formula. Attach a printout of the resulting plot. The eye diagram is useful in analyzing pulse shapes used in communication over bandlimited channels.
