For the discrete signals defined as the following: x[0]=4, x[1]=1, x[3]=-1, x[n]=0 for all other integers n. v[0]=1, v[1]=-2, v[2]=3, v[3]=-4, v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n ?
Let the probability of a bit error be p, and the length of a data frame be N. Find the probability of 1, 2, 3, and 4 bit errors occurring in the frame. a) Tabulate the results for N = 1000, 10000, and 100000 bits, for p = 10-6, 10-8, and 10-14
1) Two signals are said to be orthogonal if the integral of the product of the signals is 0 over one period of the new (multiplied) signal. Assume x(t) and y(t) are orthogonal energy signals with energy, Ex and Ey, respectively.
Gold cost about $100 an ounce in 1971. In 2007, the cost of an ounce of gold is hovering around $800. compute the average price increase for gold.
Explain the term 'multiplexing' in general and describe why it is particularly important in the transmission of PAM signals and describe the main factors upon which the maximum data rate over a channel depends.
A terrestrial radio link transmits a CDMA signal from a base station using a spreading code with a chip rate of 1.0 Mchips per seconds. The message data rate of the signal is 10 kbps.
Determine the minimum bandwidth, baud, and bandwidth efficiency for the following bit rates and modulation schemes - 8-QAM and 16-QAM. Fb = 2400 bps Fb = 4800 bps Fb = 9600 bps
