FIELD: computer engineering. SUBSTANCE: method involves generation of two three-level signals <EMI ID=0.489 HE=15 WI=54 TI=CHI> using Popov wave functions pop<SB>q</SB>(&;), which are represented by means of two orthogonal constituents pop<SB>q</SB>(&;) = cop<SB>q</SB>(&;)+isip<SB>q</SB>(&;).. Each integer k<SB>x</SB> and k<SB>y</SB> from k<SB>x,y</SB> = 0 till k<SB>x,y</SB> = q-1, in notation systems with base q = 4 and q = 8 are represented by phases &;<SB>x,y</SB> = 2pik<SB>x,y</SB>/q. Each phase &;<SB>x,y</SB> is encoded by values of signal levels cop<SB>q</SB>(2pik<SB>x,y</SB>/q) and sip<SB>q</SB>(2pik<SB>x,y</SB>/q). Values of orthogonal constituents of Popov functions cop<SB>q</SB>(&;) and sip<SB>q</SB>(&;) are detected by comparison to thresholds <EMI ID=0.490 HE=3 WI=3 TI=CHI> of respective trigonometric functions cos&; and sin&; for argument values &; = 2pik/q. Phase addition is performed by generation of signals cop<SB>q</SB>(s) and sip<SB>q</SB>(s),; phase subtraction by cop<SB>q</SB>(-s), sip<SB>q</SB>(-s),, which represent codes of sum and difference of items k<SB>x</SB> and k<SB>y</SB>.. Phase addition and subtraction follows standard equations for addition and subtraction of phases of sine waves. EFFECT: increased functional capabilities due to encoding of numbers by means of three-level signals, their addition and subtraction in notation systems with bases q=4 and q=8. 3 cl, 15 dwg, 41 tbl
