In this problem, you are required to design a 100-channel FDM multiplex for the transmission of voice signals. There are three bands available with the following frequency ranges: Band 1: 50 kHz - 110 kHz Band 2: 200 kHz - 235 kHz Band 3: 300 kHz - 308 kHz It is also required to have 2 kHz guard band between each adjacent signal to avoid signal interference (for band 1). For band 2, It is also required to have 3 kHz guard band between each adjacent signal to avoid signal interference. No guard band is to be used for band 3 frequencies. Draw a clear block diagram of your 100-channel. The diagram must show the number of stages of the multiplex, the starting and the terminal frequency of each stage, the frequency of each guard band in each band, the frequency of each user in each band. You should also describe the details of your design at the end to get full credit.
