Single-sideband modulation

<p>In <a href="/facts/Radio/XFr909M2">radio</a> communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of <a href="/facts/Signal_modulation/aAXPjINv">signal modulation</a> used to transmit information, such as an <a href="/facts/Audio_signal/rFSTI9IF">audio signal</a>, by <a href="/facts/Radio_wave/LzrVhgbn">radio waves</a>.  A refinement of <a href="/facts/Amplitude_modulation/3sTxsXk6">amplitude modulation</a>, it uses <a href="/facts/Transmitter/nFYghtKv">transmitter</a> <a href="/facts/Electric_power/w61ID9yQ">power</a> and <a href="/facts/Bandwidth_(signal_processing)/7eMDzfJI">bandwidth</a> more efficiently. Amplitude modulation produces an output signal the bandwidth of which is twice the maximum frequency of the original <a href="/facts/Baseband/yC0jJwbL">baseband</a> 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.
