Abstract	:	A kequency-domain least-squares sinusoidal signal analysis technique for determin-ing magnitude and phase at a finite collection of frequencies is proposed. Unlike previouslyreported maximum-likelihood techniques, it is exact, closed-form, applicable to any finitecollection of frequencies, and can be applied independent of window choice. It is extendedto frequency determination through iteration. The resultant algorithm improves upon pre-viously reported maximum-likelihood methods for subinterval kequency determination byreducing computational order per iteration kom N to 1, where N is the number of datapoints. Subject to a noise floor, there is no limit to achievable accuracy or discrimina-tion. The proposed extension accommodates any window whose continuous-time Fouriertransform is known. It is illustrated here with the Kaiser-Bessel window, a near-optimum....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
