Very low distortion WebMar 1, 2000 · Typical causes. Voltage waveform distortion typically relates to electronic equipment, which has an internal switch-mode power supply (SMPS) that draws a nonlinear current waveform. Whereas a linear load produces a sine wave current, the SMPS draws current pulses at only one portion of the applied voltage waveform. gyms in penrithWebMay 28, 2014 · The distortion in time is given by a n-th order polynomial (n~10), of the form t_distort = P(t). For example, consider the distortion t_distort = 8 + 12t + 6t^2 + t^3 (which is just the power series expansion of (t-2)^3). This will distort a sine-wave as follows: I want to be able to find the distortion given this distorted sine-wave. (i.e. gyms in penfield ny
