test_signal.m

% A train of impulses were generated. The first 1000 impulses have a time 
% interval of 10. The time interval for the next 1000 impulses was set to
% 30. The final 1000 impulses have a time interval of 10 again. The test
% signal was represented by the variable raw in the following code.
