Given the information about the communication channel (with distortion) and the corresponding (distorted) recording at its receiver side, design and implement the inverse channel to obtain the original (undistorted) signal at the transmitter side. Also remove the tone by using a suitable filter. System function: Has poles at z=0.95 and z=0.95; has zeros at z=0.5-0.8j and z=-0.5+0.8j.

Could you guide me on what to do without the sound file?
