摘要
A flash interpolation circuit converts a pair of periodic and orthogonal sine-signals into a stream of periodic - phase shifted sinusoidal signals, the amplitudes of which can be combined to produce useful information about the peak amplitude of the input sine-signals, independently of the signal's frequency. An interpolation factor of 4 is shown to be sufficient for measuring amplitudes with an accuracy of 5.8%.
