SDPLL-Based Frequency Estimation of a Sinusoid in Colored Noise
The problem of frequency estimation of a single sinusoid observed in colored noise is addressed. Our estimator is based on the operation of the sinusoidal digital phase-locked loop (SDPLL) which carries the frequency information in its phase error after the noisy sinusoid has been acquired by the SDPLL. We show by computer simulations that this frequency estimator beats the Cramer-Rao bound (CR...
متن کاملCalculation of Entropy for a Sinusoid with Beta-Distributed Phase
In this paper, an analytical expression is developed for the differential entropy of a sinusoid with a Beta-distributed phase angle. This particular signal model is prevalent in optical communications, however an expression for the associated differential entropy does not currently exist. The expression we derive is approximate as it relies on a series expansion for one of the key terms needed ...
متن کاملSinusoid=light bar+dark bar?
A sinusoidal grating can be viewed as a series of light and dark bars. Here we measure the contrast discrimination thresholds for light and dark bars individually, and find that the contrast discrimination thresholds for the whole sinusoid can be explained as ideal summation of the light and dark bar thresholds. We propose a model for light bar, dark bar, and sinusoidal contrast discrimination ...
متن کاملSpur-reduced digital sinusoid synthesis
This article presents and analyzes a technique for reducing the spurious signal content in digital sinusoid synthesis. Spurious-harmonic (spur) reduction is accomplished through dithering both amplitude and phase values prior to word-length reduction. The analytical approach developed for analog quantization is used to produce new bounds on spur performance in these dithered systems. Amplitude ...

toxin (1 pg/ml) or dibutyryl cyclic AMP (0.2m) to the culture medium in which the cells are propagated. The altered distribution of glycosylation in cells exposed to cholera toxin and dibutyryl cyclic AMP, which is less evident in cells exposed to conditions that restrict the expression of transformation, is also manifested in immune-precipitation reactions, in which cellular glycoproteins are ...
