Description: Let x (n) = x1 (n)+ x2 (n), x1 (n) is a narrowband signal, is defined as x1 (n) = sin (0.05πn+φ), φ is in [0, 2π) uniformly distributed interval random phase. x2 (n) is a wideband signal, which consists of a zero mean and variance of a white noise signal e (n) incentive to produce a linear filter, and its differential equation is x2 (n) = e (n)+ 2e (n-1)+ e (n-2). (1) Calculation x1 (n) and x2 (n) each of the autocorrelation function and draw the graph of a function. Accordingly appropriate delay, in order to achieve line enhancement. (2) generating a x (n) sequences. Select the appropriate μ values. Let x (n) through line enhancer. Draw the output signal y (n) and the error signal e (n) of the waveform, respectively, and x1 (n) and x2 (n) for comparison.
