Abstract :
An approximate single sideband signal for a square-law envelope detector (SL-SSB) has the form ![\\sqrt {1 + x(t)} \\cos {\\omega _{c}t + 0.5 \\arcsin [\\hat{x}(t)(1 + 0.5x(t))/(1 + x(t))]}](/images/tex/11747.gif)
, where 
is the Hilbert transform of x(t). Signal SL-SSB is constructed in accordance with the phase method of SSB signal generation; however, before amplitude modulation a dc component is added to the modulating signal, and then the signal is squarerooted. In this manner a new SL-SSB modulation technique was obtained which is also suitable for C-SSB and AM stereo broadcasting. The SLSSB spectrum is given.
