#### Dolph-Chebyshev Window Length Computation

Given a prescribed side-lobe ripple-magnitude and main-lobe width , the required window length is given by [155]

(4.52) |

For (the typical case), the denominator is close to , and we have

(4.53) |

Thus, half the time-bandwidth product in radians is approximately

(4.54) |

where is the parameter often used to design Kaiser windows (§3.9).
