Abstract

This 8-phase modulator comprises logic circuitry for converting tribits XYZ of input data into binary control signals D1, D2, D3 and D4 according to a prescribed plan, a pair of 4-phase signal generators responsive to associated pairs of control signals, and a signal source producing a pair of equal amplitude carrier signals of the same frequency and of phases which differ by 45.degree. for driving associated ones of the 4-phase generators 45.degree. out-of-phase. Equal amplitude vector signals from the two 4-phase generators are combined to produce a resultant vector signal which individually generates the phasors of an 8-phase signal set.
