The circuit shown in the figure below is part of an audio signal receiver device. The portion of this circuit that is enclosed in the red box is a frequency selective circuit that passes or reject frequencies based on the values selected for its components. In this project, you will design this frequency selective circuit by choosing the values of its components that will enable it to strongly reject one frequency (Your SR# kHz) and strongly pass another frequency (Your SR# + 2 kHz), with intermediate response for other frequencies. Thus, this circuit is a combination of a bandpass and a band reject filter. R ww R. ww w R M R 10 k Cy CX 12 mH HI Figure 1. Audio Signal Receive Circuit Project Report Should include: 1. Calculations showing that the circuit passes and rejects the selected frequencies. 2. Circuit Diagram of the filter showing the selected values 3. Derive expression of its transfer function: |H(jw)| and 8(jw) 4. Find filter Prop 6. Submit your Multisim files and your report in Black Board cutoff frequencies, bandwidth and quality factor Ri 5. Simulation using Multisim: Build the circuit in Multisim Simulation, plot the frequency response and take a screen shot (for both, voltage magnitude and phase angle) You must decide upon the analysis parameters in simulation yourself ImgT Hint: 1. Remember that only the part inside the red box is what you need. The rest will not affect your design. 2. To reject or select a specific frequency, you need to make the impedance open circuit or short circuit
