Biomechanical studies of movement kinematics and kinetics often involve the measurement of analog quantities through discrete sampling of the signal at some regular interval. The digital data which result can, in most cases, adequately represent the original signal, providing the sampling frequency is high enough to respond to the high frequency components of that signal (Winter, 1979, p. 28). The ease of computer processing of digital data is a distinct advantage over analog data. However, in… CONTINUE READING
