Abstract :
Single-sideband (SSB) and AM signals are analyzed using a waveform that can be varied in shape from a spike through a sine wave to a square wave by varying a parameter. The average sideband powers and the peak envelope powers are then calculated and compared. It is shown that the ratio of average sideband power to peak envelope power for AM is more favorable than that for SSB for `squarish´ modulating signals. However, the ratio for SSB is about 9 dB higher than it is for AM for modulating signals ranging in shape from a sine wave to a spike
