DFT by Correlation The DFT can be computed by correlating the input signal x [ i ] x[i] with sine and cosine functions at different frequencies. This approach separates the DFT into its real and ...

Optical or magnetic sensors for position and angle sensing in motion control systems generally provide sine and cosine signals for conversion. The 90° phase shift between sine and cosine allows ...

Abstract: In practical embedded implementations of the discrete Fourier transform (DFT), used for example in bio-impedance and electrical network analysers, simplification of the solution (to have a ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...

iC-Haus has created a high-speed sine-to-digital signal conditioning interpolation IC for magnetic or optical position sensors. “Linear scales and angular sensors can benefit from higher resolution ...
