An amplified portion of the radio spectrum is shown in Figure P14-4 8 . You need to hear all of the signals from 1.0 to 2.0 MHz, but there is an interfering signal at 1.8 MHz. Design a notch filter to reduce that signal by at least \(50 \mathrm{~dB}\) and not reduce the desired signal at \(1.7 \mathrm{MHz}\) by more than \(6 \mathrm{~dB}\). Use Multisim to validate your design.
