Digital complex tone generators include a first tone generator configured to generate a first digital tone with selectable first characteristics including a first frequency, a first phase, and a first amplitude; a second tone generator configured to generate a second digital tone with selectable second characteristics including a second frequency, a second phase, and a second amplitude; and a generator adder configured for combining the first tone and the second tone to provide a digital complex tone with programmable characteristics. Corresponding methods include initializing a first and second tone generators based on, respective, selected frequencies, phases, and amplitudes; iteratively generating a first digital tone and a second digital tone; and combining these two tones to provide the digital complex tone.
