Question #1 Give answer to the following questions a) Compute the null-to-null bandwidth of a 1 microsecond pulse? [5] b) Compute data rate of sequence of modulated pulses of this duration (as in part a) where each pulse is modulated with 1 bit? [5] c) Given a channel with the same bandwidth as this pulse (as in part a) and received signal to noise power ratio of 20dB, compute the Shannon capacity of the channel? [5]
