Cheburashka character named "Старуха Шапокляк" (Old Lady Shapoklyak, from French "chapeau claque", a kind of collapsible top hat). Shapoklyak is a mischievous but charming old lady. She is tall and thin, wears a hat, a dark-coloured dress, and bloomers, and carries around a pet rat, Lariska, in her purse to help her play pranks on people, though near the end of some stories she turns around and helps the protagonists. The chorus of her theme song contains her motto, "One won't ever get famous for good deeds." The rights to the Cheburashka character and image have been heavily debated in court.
Top-hat filter theoretically possible. Top-hat filters can be constructed by chaining theoretical low-band and high-band filters. In practice, an approximate top-hat filter can be constructed in analogue hardware using approximate low-band and high-band filters. In Fourier space, a top hat filter selects a band of signal of desired frequency by the specification of a lower and upper bounding frequencies. Top-hat filters are particularly easy to implement digitally. The top hat function can be generated by differentiating a linear ramp function of width formula_1. The limit of formula_1 then becomes the Dirac delta function. Its real-space form is the same as the moving
