Abstract: An electronic device is provided. The electronic device includes a communication module, a memory, and a processor operatively connected to the communication module and the memory, the processor is configured to transmit a synchronization signal for generating a synchronization marker to a first sensor device and a second sensor device, receive and store first sensor data, receive and store second sensor data, select reference data serving as a reference from among the first sensor data and the second sensor data, detect the synchronization marker, calculate a required time between synchronization markers of the reference data based on stored sampling information of the reference data and positions of the synchronization marker included in the reference data, and correct and store sampling information of the remaining sensor data other than the reference data.

Abstract: A wearable device is provided. The wearable device includes a first sensor having a plurality of electrodes, and at least one processor electrically connected to the first sensor. The at least one processor may obtain a first electrocardiogram signal by using a first sensor in a state where the wearable device is worn on a user's body, obtain an electromyogram signal from the first electrocardiogram signal, obtain a second electrocardiogram signal by filtering the electromyogram signal from the first electrocardiogram signal, determine the wearing state of the wearable device on the basis of the intensity of the electromyogram signal and the quality of the second electrocardiogram signal, and output a guide on the wearing state on the basis of a determination result.
