Chebyshev Filter

A Chebyshev filter is an electronic circuit used to selectively allow signals within a certain frequency range while blocking others. Its key feature is that it achieves a sharper transition from passband (desired frequencies) to stopband (undesired frequencies) compared to other filters. To accomplish this, it allows for some ripple or variation in the passband, which helps in maintaining a steep roll-off. Chebyshev filters are valued for their efficiency and ability to precisely target specific frequencies, making them useful in applications like audio processing and communication systems where signal clarity and selectivity are important.
