Digital wave generator capable of producing two simultaneous functions in time with the possibility of phase shift between the two, consisting of a control unit, two wave generators, two frequency generators and two output modules, the wave generators being controlled by the same master frequency, perfectly synchronized at any moment, but separate for programming their frequency, wave form, attenuation and balance, characterized by: (a) Initial phase shift between the two generators programmable between 0 (synchronism) and a complete period, with an accuracy of 1/10,000 of a period; (b) Output function selectable for each channel between: sine, square, triangle and truncated ramp; (c) Possibility of attenuating the amplitude of the output function; (d) Possibility of generating the output functions cycle by cycle or uninterruptedly; with application in Physiology and Medicine, and in those industrial fields that require the generation of two functions with a stable degree of synchronism.
