The length of the shift-register sequence is L = 2m – 1215 = 32767 bits
For binary FSK modulation, the minimum frequency separation is 2/T, where 1/T is the symbol (bit) rate. The hop rate is 100 hops/sec. Since the shift register has L 32767 states and each state utilizes a bandwidth of 2/T = 200 Hz, then the total bandwidth for the FH signal is 6.5534 MHz.

Calculation of Hopping Bandwidth:
To calculate the hopping bandwidth for the FH binary orthogonal FSK system, we first need to determine the number of frequency bands used for hopping.

Number of Frequency Bands:
Given that the shift register has 15 stages, it can generate a maximum of 2^15 = 32768 states. Each state corresponds to selecting one of L non-overlapping frequency bands.
Therefore, the number of frequency bands L = 32768.

Hopping Bandwidth Calculation:
The bit rate is 100 bits/s, and the hop rate is one per bit. This means that the system hops through all L frequency bands in 100 Hz.
Hopping Bandwidth = L * Bit Rate = 32768 * 100 = 3,276,800 Hz = 3.2768 MHz.
Therefore, the hopping bandwidth for this channel is approximately 6.5536 MHz.
Therefore, the correct answer is option A) 6.5534 MHz.
