2. (a) Suppose a radio channel occupies a bandwidth of 11 kHz. We need to multiplex 14 radio channels with guard bands of 790 Hz using FDM. Calculate the required bandwidth. 2. (b) Suppose, you have 11 channels, each of 55 MBps. You have to use synchronous TDM to multiplex these channels. If each channel passes 3 characters during each input slot, answer the following: • What is the size of an output frame in bits? • What is the input bit duration? • What is the output slot duration? • What is the output bit duration? • What is the output frame rate? • What is the output data rate?
