Networks Integrated circuit (chip) \(R C\) networks are used at parallel data ports to suppress radio frequency noise. In a certain application, RF noise at \(3.2 \mathrm{MHz}\) is interfering with a 4-bit parallel data signal operating at \(1.1 \mathrm{MHz}\). A chip \(R C\) network is to be used to reduce the RF noise on the parallel bus by at least \(7 \mathrm{~dB}\) without reducing the data signals by more than \(2 \mathrm{~dB}\). A vendor offers a family of chip \(R C\) networks connected as shown in Figure P12-65. The available circuit parameters are shown in Table P12-65. Select the part number that best meets the noise suppression requirements.
