High precision phase measurement using reduced sine and cosine tables
The author proposes a microprocessor-based hardware implementation of a high-precision phase measurement technique. The hardware implementation requires two reduced tables: a sine table and a cosine table. If each table has (i(i+5)/2) entries, then the phase can be accurately determined even if the signals are distorted by any number of harmonics in the range of 2nd through ith harmonics. This design could easily be fabricated to make a 28-pin custom VLSI chip.<>
