Linear Modulation: Consider a random data stream of independent binary digits, where O's and 1's are equally probable. Suppose that these data are encoded using polar-type signaling with pulse waveforms x1(t) = A(2(t - T/2)/T), xo(t) = -A(2(t - T/2)/T) (a) Sketch the transmitted waveform corresponding to 0111000. (b) Find a pulse g(t) and data amplitudes X, to represent these signals. (c) Find and sketch the PSD. (d) Find the first-null bandwidth and spectral efficiency.
