Problem 220. Signal filtering
You are given a vector, containing a superposition of target signal and white gaussian noise. Return a vector, containing the estimated signal, assuming the following conditions:
- signal-to-noise ratio is greater than 1;
- the sampling rate is at least 100 times greater than the target signal bandwidth.
The correlation coefficient of the resulting signal and the initial signal should be at least 0.95.

It seems that function chirp isn't working. Gives following error:
Undefined function 'chirp' for input arguments of type 'double'.
Error in Test2 (line 1)
y = chirp(0:0.0001:0.9999,50,1,150)' + randn(10000,1);
