Resumo	The Chebyshev filter is a signal processing filter that achieves a sharper cutoff frequency response than Butterworth filters by allowing controlled ripple in the passband (Type I) or stopband (Type II). Developed by Wilhelm Cauer and based on Chebyshev polynomials, these filters are widely used when a steep transition is needed with acceptable amplitude ripple.	The Wiener filter is an optimal linear filter that minimizes mean-square error between the desired signal and the filter output given knowledge of signal and noise statistics. Developed by Norbert Wiener in 1949, it provides the theoretical foundation for optimal filtering and remains the benchmark against which all other linear filtering methods are compared.
