DSB (Double Sideband)

Double Sideband (DSB) is a type of radio transmission method where a carrier signal and two sidebands—containing the actual information—are transmitted simultaneously. The carrier provides a reference frequency, while the sidebands carry the modulated audio or data signal. In DSB, both sidebands are transmitted together, which efficiently uses power but requires additional steps like filtering or modulation techniques to extract the original message at the receiver. DSB is commonly used in traditional AM radio broadcasting, balancing signal clarity with effective power use.
