In telecommunications, a carrier signal, carrier wave, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information.This carrier wave is usually a much higher frequency than the input signal.n the case of single-sideband modulation (SSB), the carrier is suppressed (and in some forms of SSB, eliminated). The carrier must be reintroduced at the receiver by a beat frequency oscillator (BFO).
1.) Carrier Frequency (Hz) -- Most fixed at 2500Hz to yield a 200Î¼sec burst duration. 2.) Burst Frequency (bps) (like pulse freq.) 3.) Duty Cycle -- % of burst duration to the interburst interval during contract cycle (on-time).
