Abstract:
An information processing system of the type having a first information processing apparatus to send data, a second information processing apparatus to receive and process said data, and a third information processing apparatus connected to said first information processing apparatus, wherein said first information processing apparatus contains a means to modulate current in response to data to be transmitted and a means to supply a first current which has been modulated by said modulating means to said second information processing apparatus; said second information processing apparatus contains a means to input a third current which has been synthesized from said first current supplied from said supply means and a second current output from said third information processing apparatus, a means to estimate said second current, a means to extract said first current by subtracting said second current (which has been estimated by said estimating means) from said third current which has been entered from said input means, and a means to demodulate said data from said first current extracted by said extracting means; and said third information processing apparatus contains a means to execute processing in response to instructions from said first information processing apparatus.
