Why SSB is not suitable for video transmission?
When carrier is shifted to bandpass, this one sided bandwidth becomes 9 MHz. This is nearly ten times as large as the total bandwidth occupied by all the channels of the AM radio. Use of SSB modulation would cut this in half but SSB is not used for video signals because of the complexity of the SSB receivers.
Can we use SSB for transmission?
SSB modulation is a way to transmit information by radio waves. It uses transmitter power and bandwidth more efficiently than amplitude modulation by avoiding the bandwidth increase that amplitude modulation produces. It also doesn't waste power on a carrier.
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.
