For your design, sampling frequency is fixed at 20,000Hz. The 3 filters MUST satisfy the following: i. They are all bandpass filters with cutoff frequencies in the range 50Hz to 9950Hz ii. They are FIR filters, all with length of 65 points, employing a Chebyshev window with sidelobe specification of 80dB You must decide on the cutoff frequencies for each filter, the 0dB reference gain value and the appropriate gain for each filter to achieve the objective of reversing the hearing loss
