Why single sideband modulation is practically difficult?
Amplitude modulation produces an output signal the bandwidth of which is twice the maximum frequency of the original baseband signal. Single-sideband modulation avoids this bandwidth increase, and the power wasted on a carrier, at the cost of increased device complexity and more difficult tuning at the receiver.
How to generate SSB signal?
There are two methods of generating SSB signals: one using a high pass or low pass filter, and the other using a Hilbert transformer.
What is the main benefit of SSB?
The advantage of SSB is its narrow bandwidth and higher power efficiency than the other voice modes. The Other Options: The wide bandwidth of FM provides a higher fidelity, while the fidelity of SSB suffers with narrower bandwidth, so option 'A' is out.
What is SSB frequency?
Single Side Band uses High Frequency (HF) from 3 to 30 Mhz, with wavelengths of 10 to 100 meters (30 to 330 feet). These longer wavelength, low frequency signals will bounce off things, including the upper atmosphere. This bounce allows the radio waves to travel very long distances.
