The amplified signals are distorted by the presence of muscle artifacts and power line interference; thus, these noises are removed using filter stages 1 and 2 Within this research, a low-pass filter with a cutoff frequency of 33HZ was used to remove muscle artifacts, and a twin-T notch filter with a cutoff frequency of 60HZ was utilized to eliminate power line interference.
