In [3], Lee and Asada analyzed the design problem on the basis of 2-input-gate unit delay within a ripple carry adder structure.
For a certain carrier frequency [f.sub.C], the N-stage delay line with a unit delay of 1/(N x [f.sub.C]) converts the quantized phase X to the rising-edge lag [PHI] of the carrier clock.
For a certain carrier clock, the N-stage delay line with a unit delay of 1/(N x [f.sub.C]) converts the quantized phase X to the rising-edge lag of the carrier clock.
To ensure modulation performances, the unit delay of delay lines needs to be accurate.
The phase difference between the periodic clock input and 90[degrees]-shifted clock corresponding to K unit delays is measured and converted to an error voltage by an XOR gate followed by a low-pass filter (LPF) and a sequent comparator.
In this figure, each block labelled T, often shown as [z.sup.-1] in signal processing texts, represents a unit delay element, and each block labelled h represents a weighting coefficient by which the delayed signals are multiplied prior to summation.
