SINGLE SIDEBAND TRANSMISSION 



65 



Fig. 1 — Idealized transfer admittance characteristic. (Band pass system with no 

 delay distortion; Fc is the carrier and 5 the fundamental dotting frequency.) 



Fig. 2 — Graphical analysis of transmission characteristic. (The sum of these 

 characteristics equals that in Fig. 1. The upper gives received signals with carrier 

 in phase, and the lower, in quadrature with the sent wave.) 



Fig. 3 — Equivalent low-pass filter char- 

 acteristic. (Used in computing enve- 

 lopes of received signals for single side- 

 band transmission.)

 acteristic. (Used in computing enve- 

 lopes of received signals with mid-band 

 carrier.)
