This two-channel microprocessed pulse amplitude modulation system generates two different envelope waveforms (triangular and elliptical) and allows programming and visualizing of its main parameters: pulse width (0.1–10 ms), pulse frequency (0.1–10 kHz), modulation frequency (0.3–10 Hz), current intensity (up to 20 mA), and the amplitude modulation index (0–100%). In vivo experiments with 5 normal persons have shown that it is possible to elicit a moving fused phantom image with good resolution. A triangular envelope is good for straight line sensations while the elliptical one is more comfortable and has better resolution for all kinds of moving images.
