1. A device for measuring a biological signal, the device comprising:
- electrodes configured to collect measurements from a subject;
a single differential amplifier configured to measure a size of the measured biological signal; and
a controller configured to;
select electrode combinations, each of the electrode combinations including at least two electrodes selected from the electrodes;
control the single differential amplifier to connect to at least two electrodes included in each of the selected electrode combinations, wherein the single differential amplifier is configured to measure respective signal sizes from the at least two electrodes; and
determine, as an optimal electrode combination, a combination of a first electrode and a second electrode by comparing the respective signal sizes measured for each of the selected electrode combinations with each other, the optimal electrode combination having a determined largest biological signal size based on a result of the comparing.
