The cochlear implant is intended for patients with deafness due to malfunction of the sensory cells of the cochlea in the inner ear (Loeb, 1985). These devices use a microphone for picking up sound and a processor for converting it to electrical signals, and they transmit these signals to the nervous system. A cochlear implant relies on the fact that many of the auditory nerve fibers remain intact in patients with this form of hearing loss. The overall transmission from microphone to nerve cells is represented by the gain function

                                 \(\mathbf{H}(j \omega)=\frac{10(j \omega / 50+1)}{(j \omega / 2+1)(j \omega / 20+1)(j \omega / 80+1)}\)

Plot the magnitude Bode diagram for \(\mathbf{H}(j \omega)\) for \(1 \leq \omega \leq 100\).
