Given a speech equalizer shown in Figure to compensate midrange frequency loss of hearing:

Sampling rate = 8,000 Hz

Bandpass FIR filter with Hamming window

Frequency range to be emphasized = 1,500–2,000 Hz

Lower stopband = 0–1,000 Hz

Upper stopband = 2,500–4,000 Hz

Passband ripple = 0.1 dB

Stopband attenuation = 45 dB,

determine the filter length and the lower and upper cutoff frequencies.
