On analytic signals with nonnegative instantaneous frequencies
In this paper, we characterize all analytic signals with band-limited amplitudes and polynomial phases. We show that a signal with band-limited amplitude and polynomial phase is analytic if and only if it has nonneg-ative constant instantaneous frequency, i.e., the derivative of the phase is a nonnegative constant, and the constant is greater than or equal to the minimum bandwidth of the amplit...
متن کاملThe Structure of Instantaneous Frequencies of Periodic Analytic Signals
The structure of analytic signals is investigated by means of the relation between analytic signals and functions in the Hardy space. It is shown that an analytic signal is made up of two parts, one depends on the amplitude of the signal and another on the boundary value of an inner function. Based on this result, properties of the instantaneous frequencies of these two parts are studied, and i...
متن کاملExtraction of Instantaneous and RMS Sinusoidal Jitter Using an Analytic Signal Method
This paper describes a new method for extracting both instantaneous and rms sinusoidal jitter from phase-locked loops (PLL) output signals. The method is based on analytic signal theory and utilizes the Hilbert transform to extract phase information from a PLL signal. Both the theoretical basis and fundamental concepts of the new method are explained. A unified review of conventional methods is...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولa comparison between the horizontal gradient of analytic signal method and the analytic signal-euler deconvolution combined method using synthetic data in interpretation of magnetic geological structures
the analytic signal method is a semiautomatic method for estimating the location of causative bodies in magnetic and gravity methods. the application of analytic signal for interpretation of two dimensional (2d) structures was introduced by nabighian (1972). the analytic signal is defined as a complex function in which the real and imaginary parts are a pair of hilbert transforms. in other word...
