Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.

See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true.

Rainbow Mystery is a terrific fun from the creators of Rainbow Web! This time you join a young fairy of flowers, Lily, on her quest to break the curse in this swap-and-match puzzle. Some time passes and the evil wizards turn the Rainbow world into a tainted landscape. But Lily is determined to bring life and color into this world again. Help Lily solve puzzles on her way while keeping an eye out for magical power-ups, and bonuses. They will give you the edge you need to twist your way through 70 levels of joy! Featuring stunning graphics, amazing animations and 3 different game modes, Rainbow Mystery is bursting with puzzle-solving fun!

The goal of the game is to break the curse plaguing the Rainbow lands. You do this by solving puzzles as your travel through this country. To solve a puzzle, you should swap and match flowers to make a line of more than three flowers that explode, adding to your score. The more flowers explode at one click, the greater your score grows. Additional challenge comes with colored cells that some flowers sit on. Explode such flowers in the first place to clear up those cells. Once you manage to do this, you’ll be able to make an elixir, break the curse, and continue your adventure on the next level. Many of the title’s 70 levels add new challenges. On some levels, for example, there are puzzles with an artifact like a key in the center. So, you’ll have to do some sophisticated swap-and-match to bring the artifact down to the bottom of the puzzle. Rainbow Mystery lets you explore the Rainbow world and in Quest and Duel modes.

- Three different game modes: Timed, Untimed, and Duel;
- 70 levels, each with its own unique puzzle;
- Lots of power-ups and bonuses;
- Rich, liquid-smooth graphics, plus 14 animations;
- Author’s music to enhance playing experience;
- Addictive gameplay.

In the heart of a wonderland, surrounded by crystal clear lakes, mighty stone, and age-old forests there existed the Rainbow Kingdom.

But as it usually happens in all fairy tails, there appears someone, who is not pleased when things go right. In Rainbow Web this is Spider, a wicked and mighty wizard. It casts a spell on the land and all fairy tail creatures and spins a web around.

The poor Rainbow citizens are waiting for a hero who can remove the spell and bring peace to their kingdom.


That hero is you, and you must free letters from the magic web to restore the real names of the magic scenery. Once all the names are restored, the kingdom will be back to sunlight and rainbows will color the sky.

Come through 60 levels to break the spell and return the Rainbow Kingdom to sunshine!
