Draw the graph of the NRZ-L scheme using each of the following data streams, assuming that the last signa11evel has been positive. From the graphs, guess the bandwidth for this scheme using the average number of changes in the signal level. Compare your guess with the corresp.onding entry in Table 4.1. a. 00000000 b. 11111111 c. 01010101

For a single-layer perceptron, which statement is true for a viable error function? Here w.x denotes the weighted sum of inputs. E=1 for any input for which the output is 1 and the classification is incorrect. E=-w.x for any input for which the output is 1 and the classification is correct. E=-1 for any input for which the output is 1 and the classification is correct. E=w.x for any input for which the output is 1 and the classification is incorrect.

V(t) = Vp sin(ωt +/- ɑ)Vp = 12mVω = 2πf --> ω = 2π * 2kHz --> ω = 12566Ɑ = 3π / 4 * (180/π) --> 135  --> Ɑ = 135° degreesV(t) = 12sin(12566t + 135)mV   is the answer correct?

Write a Matlab script assignment_X_0402.m, where X is your name a. Generate a sine signal (using plot function) of 3 kHz, in the interval of tmin=0 to tmax=2*T (using T/200 as a time increment), where: X(t) = (1/3)sin(2äft). b. Using the subplot function in Matlab, for Fs = 10 kHz do sampling of X(t) and plot both original (use plot) and sampled signal (use stem).
