SSB Full Form is Service Selection Board. This refers to the series of interviews and tests a candidate goes through in order to be selected into the Indian Armed Force. The tests comprise of screening test, psychological test, interview, and group testing officers or GTO test. The SSB basically analyses the compatibility and potential of candidates for commissioning into the Armed Force.
SSB Full Form also refers to Single Side Band Modulation. This is a refined form of amplitude modulation. It offers better bandwidth and transmitter power. Unlike AM (amplitude modulation), SSB does not apply doubling of bandwidth. In other words, as the name indicates, SSB only uses single side band for every audio path in order to give out the final signal. It offers effective communications and is used much in analog TV signals.
