Using a single PLL, design a system that has an output frequency equal to 7/3 f₀, Where f₀ is the input frequency. Describe fully, by sketching, the output of the VCO for your design. Draw the spectrum at the VCO output and at any other point in the system necessary to explain the operation of your design. Describe any filters used in your design by defining the center frequency and the appropriate bandwidth of each.
