Biological-signal-processing system, signal-processing device, computer program, and method for generating biological signal

A signal processing device configured to execute signal processing,

• the signal processing comprising:
• acquiring a first biological signal of p (p is an integer of 2 or larger) channels from m (m is an integer of 3 or larger) electrodes attached in a first arrangement to a living body;
• and
• inputting the first biological signal of the p channels into a generative model, and outputting a second biological signal of q (q is an integer of 2 or larger) channels, from the generative model, wherein
• the second biological signal of the q channels is a signal corresponding to signals obtained from n (n is an integer of 3 or larger) electrodes attached in a second arrangement to the living body,
• the second arrangement is an electrode arrangement different from the first arrangement in at least one of the number of electrodes and an attachment position, and
• the generative model is configured to output the second biological signal of the q channels when the first biological signal of the p channels has been inputted.
