Signal-to-Distorion Ratio
September 13th Fact-of-the-DayIntermodulation distortion is the principal type of distortion generated in SSB transmitters. Intermodulation distortion usually is measured with two test frequencies. The signal-to-distortion ratio is the ratio of the amplitude of one frequency of two equal-amplitude test frequencies to a third-order distortion product. That ratio usually is expressed in decibels in transmitter specifications. ©2004 Martek International All rights reserved.
