A discrete time signal x[k] is given by:
x[k] = 5, for -4≤k≤4
x[k] = 0, for |k|>4.

Solution:
An FH binary orthogonal FSK system employs an m=15 stage linear feedback shift register that generates an ML sequence. Each state of the shift register selects one of L non-overlapping frequency bands in the hopping pattern. The bit rate is 100 bits/s. The demodulator employs non-coherent detection. If the hop rate is one per bit, the hopping bandwidth for this channel is
