1. Design a custom FIR band-pass filter using the Fourier series and the Hanning window. The filter should be of order 8. We need to pass the signal in two audio bands 400-1600Hz and 4000-8000Hz and attenuate it elsewhere. The sampling frequency is 20 kHz. a) Calculate with pencil and paper the impulse response of the filter and the numerical values of the coefficients.
