Abstract :
An economical means of constructing a Fourier analyzer utgizing polarity correlation is described. Only one sinusoidal Oscillator and its quadrature function are required, but one clock is needed for each pair of cosine and sine coefficients. Included are analyses of the convergence time for a given fractional error probability and of the error variance for RC averaging.
