![]() Antoniou describes the time domain representation of the Chebyshev window as: Several sources even indicate that there is no direct time domain expression for the chebyshev window, however this is not true. Most windows, however, are defined in time domain (not frequency domain like the example above). Where and is the required sidelobe attenuation in dB (e.g. The majority of sources that describe the Chebyshev window describe it in frequency domain, e.g. the side-lobe height is the same at all frequencies. ![]() Another property of the Chebyshev window is that it is equi-ripple, i.e. Width for a given side-lobe attenutation. It is optimal in that it has a minimum main-lobe The Dolph-Chebyshev window (a.k.a Chebyshev window) is used in signal processing. Implementing the Dolph-Chebyshev Window Introduction §Ĭhebyshev's name can be alternatively transliterated as Chebychev, Chebysheff, Chebyshov, Tchebychev or Tchebycheff, or Tschebyschev or Tschebyscheff, which often makes it difficult to find anything about him in search engines.
