EN In this paper design of a miniature, low cost surface electromyography amplifier is proposed. Presented device can be considered to be resistant to common environmental interferences. Proposed design consists of main amplifier board and second board containing DRL circuit and reference voltage source. Major disturbance is provided by mains (50/60 Hz) - most emphasized interference in this paper. Design includes appropriate set of filtration circuits. Moreover comparison with four commercial and hobbyist devices is provided.
