a. A microwave radio link operates over a bandwidth of 400 MHz at C band. The link carries a number of channels of data using FDMA. Each channel has an RF bandwidth of 36 MHz and 4 MHz guard bands are needed between channels. What is the maximum number of channels that the link can carry?

Each channel occupies a frequency space of f_channel given by the sum of the channel bandwidth f_BW = 36MHz and the guard band frequency space f_GB = 4MHz so we can write

The number of channels N_channel in the allocated C Band bandwidth is ...
