**Homework Assignment 9 **

Due Oct. 27, 2000

- Problem 8.1. For part (d) use a Blackman window rather than a Bartlett
window.

- We wish to design an FIR bandpass filter satisfying the following
specifications:

Design this filter using a Kaiser window.

- Find for the Kaiser window to meet the passband and stopband
attenuations.
- Find the length of the filter to meet the transition band widths.

- Find and plot the impulse response of the filter.

- Plot the gain of the filter and show that it meets the
specifications.

- Repeat Problem 3 using the Remez algorithm for designing an equiripple
FIR filter (the
`remez()` function if MATLAB).

- Find the length M of the filter using Equation 8.2.94 or 8.2.95
of the Text.

- Find the impulse respone h(n) using the
`remez()`
function if MATLAB.

- Plot the gain of the filter and show that it meets the
specifications.
