Figure P7.39 is the ideal, desired frequency response amplitude for a bandpass filter to be designed as a Type I FIR filter h[n], with DTFT H(e^jω) that approximates H_d(e^jω) and meets the following constraints:

The resulting filter h[n] is to minimize the maximum weighted error and therefore must satisfy the alternation theorem.

Determine and sketch an appropriate choice for the weighting function to use with the Parks–McClellan algorithm.
